This prop is derived from the [d3.formatLocale](https://github.com/d3/d3-format#formatLocale) data structure specification. When left unspecified, each individual nested prop will default to a pre-determined value. • markdown_options (record with the fields: 'link_target: string | value equal to: '_blank', '_parent', '_self', '_top' (optional)', 'html: boolean (optional)'; default { link_target: '_blank', html: false }) - The `markdown_options` property allows customization of the markdown cells behavior. • css (list with values of type: record with the fields: 'selector: string (required)', 'rule: string (required)'; default []) - The `css` property is a way to embed CSS selectors and rules onto the page. We recommend starting with the `style_*` properties before using this `css` property. Example: [ {"selector": ".dash-spreadsheet", "rule": 'font-family: "monospace"'} ] • data (list with values of type: record) - The contents of the table. The keys of each item in data should match the column IDs. Each item can also have an 'id' key, whose value is its row ID. If there is a column with ID='id' this will display the row ID, otherwise it is just used to reference the row for selections, filtering, etc. Example: [ {'column-1': 4.5, 'column-2': 'montreal', 'column-3': 'canada'}, {'column-1': 8, 'column-2': 'boston', 'column-3': 'america'} ] • data_previous (list with values of type: record) - The previous state of `data`. `data_previous` has the same structure as `data` and it will be updated whenever `data` changes, either through a callback or by editing the table. This is a read-only property: setting this property will not have any impact on the table. • data_timestamp (number) - The unix timestamp when the data was last edited. Use this property with other timestamp properties (such as `n_clicks_timestamp` in `dash_html_components`) to determine which property has changed within a callback. • editable (boolean; default false) - If True, then the data in all of the cells is editable. When `editable` is True, particular columns can be made uneditable by setting `editable` to `False` inside the `columns` property. If False, then the data in all of the cells is uneditable. When `editable` is False, particular columns can be made editable by setting `editable` to `True` inside the `columns` property. • end_cell (record with the fields: 'row: number (optional)', 'column: number (optional)', 'row_id: string | number (optional)', 'column_id: string (optional)') - When selecting multiple cells (via clicking on a cell and then shift-clicking on another cell), `end_cell` represents the row / column coordinates and IDs of the cell in one of the corners of the region. `start_cell` represents the coordinates of the other corner. • export_columns (value equal to: 'all', 'visible'; default visible) - Denotes the columns that will be used in the export data file.

If `'none'`, there will be no header. If `'display'`, then the header of the data file will be be how it is currently displayed. Note that `'display'` is only supported for `'xlsx'` export_format and will behave like `'names'` for `'csv'` export format. If `'ids'` or `'names'`, then the headers of data file will be the column id or the column names, respectively • fill_width (boolean; default true) - `fill_width` toggles between a set of CSS for two common behaviors: True: The table container's width will grow to fill the available space; False: The table container's width will equal the width of its content. • hidden_columns (list with values of type: string) - List of columns ids of the columns that are currently hidden. See the associated nested prop `columns.hideable`. • is_focused (boolean) - If True, then the `active_cell` is in a focused state. • merge_duplicate_headers (boolean) - If True, then column headers that have neighbors with duplicate names will be merged into a single cell. This will be applied for single column headers and multi-column headers. • fixed_columns (record with the fields: 'data: value equal to: '0' (optional)', 'headers: value equal to: 'false' (optional)' | record with the fields: 'data: number (optional)', 'headers: value equal to: 'true' (required)'; default { headers: false, data: 0 }) - `fixed_columns` will "fix" the set of columns so that they remain visible when scrolling horizontally across the unfixed columns. `fixed_columns` fixes columns from left-to-right. If `headers` is False, no columns are fixed. If `headers` is True, all operation columns (see `row_deletable` and `row_selectable`) are fixed. Additional data columns can be fixed by assigning a number to `data`. Note that fixing columns introduces some changes to the underlying markup of the table and may impact the way that your columns are rendered or sized. View the documentation examples to learn more. • fixed_rows (record with the fields: 'data: value equal to: '0' (optional)', 'headers: value equal to: 'false' (optional)' | record with the fields: 'data: number (optional)', 'headers: value equal to: 'true' (required)'; default { headers: false, data: 0 }) - `fixed_rows` will "fix" the set of rows so that they remain visible when scrolling vertically down the table. `fixed_rows` fixes rows from top-to-bottom, starting from the headers. If `headers` is False, no rows are fixed. If `headers` is True, all header and filter rows (see `filter_action`) are fixed. Additional data rows can be fixed by assigning a number to `data`. Note that fixing rows introduces some changes to the underlying markup of the table and may impact the way that your columns are rendered or sized. View the documentation examples to learn more. • column_selectable (value equal to: 'single', 'multi', 'false'; default false) - If `single`, then the user can select a single column or group of merged columns via the radio button that will appear in the header rows. If `multi`, then the user can select multiple columns or groups of merged columns via the checkbox that will appear in the header rows. If false, then the user will not be able to select columns and no input will appear in the header rows. When a column is selected, its id will be contained in `selected_columns` and `derived_viewport_selected_columns`. • row_deletable (boolean) - If True, then a `x` will appear next to each `row` and the user can delete the row. • cell_selectable (boolean; default true) - If True (default), then it is possible to click and navigate table cells. • row_selectable (value equal to: 'single', 'multi', 'false'; default false) - If `single`, then the user can select a single row via a radio button that will appear next to each row. If `multi`, then the user can select multiple rows via a checkbox that will appear next to each row. If false, then the user will not be able to select rows and no additional UI elements will appear. When a row is selected, its index will be contained in `selected_rows`. • selected_cells (list with values of type: record with the fields: 'row: number (optional)', 'column: number (optional)', 'row_id: string | number (optional)', 'column_id: string (optional)'; default []) - `selected_cells` represents the set of cells that are selected, as an array of objects, each item similar to `active_cell`. Multiple cells can be selected by holding down shift and clicking on a different cell or holding down shift and navigating with the arrow keys. • selected_rows (list with values of type: number; default []) - `selected_rows` contains the indices of rows that are selected via the UI elements that appear when `row_selectable` is `'single'` or `'multi'`. • selected_columns (list with values of type: string; default []) - `selected_columns` contains the ids of columns that are selected via the UI elements that appear when `column_selectable` is `'single' or 'multi'`. • selected_row_ids (list with values of type: string | number; default []) - `selected_row_ids` contains the ids of rows that are selected via the UI elements that appear when `row_selectable` is `'single'` or `'multi'`. • start_cell (record with the fields: 'row: number (optional)', 'column: number (optional)', 'row_id: string | number (optional)', 'column_id: string (optional)') - When selecting multiple cells (via clicking on a cell and then shift-clicking on another cell), `start_cell` represents the [row, column] coordinates of the cell in one of the corners of the region. `end_cell` represents the coordinates of the other corner. • style_as_list_view (boolean; default false) - If True, then the table will be styled like a list view and not have borders between the columns. • page_action (value equal to: 'custom', 'native', 'none'; default native) - `page_action` refers to a mode of the table where not all of the rows are displayed at once: only a subset are displayed (a "page") and the next subset of rows can viewed by clicking "Next" or "Previous" buttons at the bottom of the page. Pagination is used to improve performance: instead of rendering all of the rows at once (which can be expensive), we only display a subset of them. With pagination, we can either page through data that exists in the table (e.g. page through `10,000` rows in `data` `100` rows at a time) or we can update the data on-the-fly with callbacks when the user clicks on the "Previous" or "Next" buttons. These modes can be toggled with this `page_action` parameter: `'native'`: all data is passed to the table up-front, paging logic is handled by the table; `'custom'`: data is passed to the table one page at a time, paging logic is handled via callbacks; `'none'`: disables paging, render all of the data at once. • page_current (number; default 0) - `page_current` represents which page the user is on. Use this property to index through data in your callbacks with backend paging. • page_count (number) - `page_count` represents the number of the pages in the paginated table. This is really only useful when performing backend pagination, since the front end is able to use the full size of the table to calculate the number of pages. • page_size (number; default 250) - `page_size` represents the number of rows that will be displayed on a particular page when `page_action` is `'custom'` or `'native'` • dropdown (dict with values of type: record with the fields: 'clearable: boolean (optional)', 'options: list with values of type: record with the fields: 'label: string (required)', 'value: number | string | boolean (required)' (required)'; default {}) - `dropdown` specifies dropdown options for different columns. Each entry refers to the column ID. The `clearable` property defines whether the value can be deleted. The `options` property refers to the `options` of the dropdown. • dropdown_conditional (list with values of type: record with the fields: 'clearable: boolean (optional)', 'if: record with the fields: 'column_id: string (optional)', 'filter_query: string (optional)' (optional)', 'options: list with values of type: record with the fields: 'label: string (required)', 'value: number | string | boolean (required)' (required)'; default []) - `dropdown_conditional` specifies dropdown options in various columns and cells. This property allows you to specify different dropdowns depending on certain conditions. For example, you may render different "city" dropdowns in a row depending on the current value in the "state" column. • dropdown_data (list with values of type: dict with values of type: record with the fields: 'clearable: boolean (optional)', 'options: list with values of type: record with the fields: 'label: string (required)', 'value: number | string | boolean (required)' (required)'; default []) - `dropdown_data` specifies dropdown options on a row-by-row, column-by-column basis. Each item in the array corresponds to the corresponding dropdowns for the `data` item at the same index. Each entry in the item refers to the Column ID. • tooltip (dict with values of type: string | record with the fields: 'delay: number (optional)', 'duration: number (optional)', 'type: value equal to: 'text', 'markdown' (optional)', 'use_with: value equal to: 'both', 'data', 'header' (optional)', 'value: string (required)'; default {}) - `tooltip` is the column based tooltip configuration applied to all rows. The key is the column id and the value is a tooltip configuration. Example: {i: {'value': i, 'use_with: 'both'} for i in df.columns} • tooltip_conditional (list with values of type: record with the fields: 'delay: number (optional)', 'duration: number (optional)', 'if: record with the fields: 'column_id: string (optional)', 'filter_query: string (optional)', 'row_index: number | value equal to: 'odd', 'even' (optional)' (required)', 'type: value equal to: 'text', 'markdown' (optional)', 'value: string (required)'; default []) - `tooltip_conditional` represents the tooltip shown for different columns and cells. This property allows you to specify different tooltips depending on certain conditions. For example, you may have different tooltips in the same column based on the value of a certain data property. Priority is from first to last defined conditional tooltip in the list. Higher priority (more specific) conditional tooltips should be put at the beginning of the list. • tooltip_data (list with values of type: dict with values of type: string | record with the fields: 'delay: number (optional)', 'duration: number (optional)', 'type: value equal to: 'text', 'markdown' (optional)', 'value: string (required)'; default []) - `tooltip_data` represents the tooltip shown for different columns and cells. A list of dicts for which each key is a column id and the value is a tooltip configuration. • tooltip_header (dict with values of type: string | record with the fields: 'delay: number (optional)', 'duration: number (optional)', 'type: value equal to: 'text', 'markdown' (optional)', 'value: string (required)' | list with values of type: value equal to: 'null' | string | record with the fields: 'delay: number (optional)', 'duration: number (optional)', 'type: value equal to: 'text', 'markdown' (optional)', 'value: string (required)'; default {}) - `tooltip_header` represents the tooltip shown for each header column and optionally each header row. Example to show long column names in a tooltip: {i: i for i in df.columns}. Example to show different column names in a tooltip: {'Rep': 'Republican', 'Dem': 'Democrat'}. If the table has multiple rows of headers, then use a list as the value of the `tooltip_header` items. • tooltip_delay (number; default 350) - `tooltip_delay` represents the table-wide delay in milliseconds before the tooltip is shown when hovering a cell. If set to `None`, the tooltip will be shown immediately. Defaults to 350. • tooltip_duration (number; default 2000) - `tooltip_duration` represents the table-wide duration in milliseconds during which the tooltip will be displayed when hovering a cell. If set to `None`, the tooltip will not disappear. Defaults to 2000. • filter_query (string; default ) - If `filter_action` is enabled, then the current filtering string is represented in this `filter_query` property. • filter_action (value equal to: 'custom', 'native', 'none' | record with the fields: 'type: value equal to: 'custom', 'native' (required)', 'operator: value equal to: 'and', 'or' (optional)'; default none) - The `filter_action` property controls the behavior of the `filtering` UI. If `'none'`, then the filtering UI is not displayed. If `'native'`, then the filtering UI is displayed and the filtering logic is handled by the table. That is, it is performed on the data that exists in the `data` property. If `'custom'`, then the filtering UI is displayed but it is the responsibility of the developer to program the filtering through a callback (where `filter_query` or `derived_filter_query_structure` would be the input and `data` would be the output). • filter_options (record with the field: 'case: value equal to: 'sensitive', 'insensitive' (optional)'; default {}) - There are two `filter_options` props in the table. This is the table-level filter_options prop and there is also the column-level `filter_options` prop. These props determine whether the applicable filter relational operators will default to `sensitive` or `insensitive` comparison. If the column-level `filter_options` prop is set it overrides the table-level `filter_options` prop for that column. • sort_action (value equal to: 'custom', 'native', 'none'; default none) - The `sort_action` property enables data to be sorted on a per-column basis. If `'none'`, then the sorting UI is not displayed. If `'native'`, then the sorting UI is displayed and the sorting logic is handled by the table. That is, it is performed on the data that exists in the `data` property. If `'custom'`, the the sorting UI is displayed but it is the responsibility of the developer to program the sorting through a callback (where `sort_by` would be the input and `data` would be the output). Clicking on the sort arrows will update the `sort_by` property. • sort_mode (value equal to: 'single', 'multi'; default single) - Sorting can be performed across multiple columns (e.g. sort by country, sort within each country, sort by year) or by a single column. NOTE - With multi-column sort, it's currently not possible to determine the order in which the columns were sorted through the UI. See [https://github.com/plotly/dash-table/issues/170](https://github.com/plotly/dash-table/issues/170) • sort_by (list with values of type: record with the fields: 'column_id: string (required)', 'direction: value equal to: 'asc', 'desc' (required)'; default []) - `sort_by` describes the current state of the sorting UI. That is, if the user clicked on the sort arrow of a column, then this property will be updated with the column ID and the direction (`asc` or `desc`) of the sort. For multi-column sorting, this will be a list of sorting parameters, in the order in which they were clicked. • sort_as_null (list with values of type: string | number | boolean; default []) - An array of string, number and boolean values that are treated as `None` (i.e. ignored and always displayed last) when sorting. This value will be used by columns without `sort_as_null`. Defaults to `[]`. • style_table (record; default {}) - CSS styles to be applied to the outer `table` container. This is commonly used for setting properties like the width or the height of the table. • style_cell (record) - CSS styles to be applied to each individual cell of the table. This includes the header cells, the `data` cells, and the filter cells. • style_data (record) - CSS styles to be applied to each individual data cell. That is, unlike `style_cell`, it excludes the header and filter cells. • style_filter (record) - CSS styles to be applied to the filter cells. Note that this may change in the future as we build out a more complex filtering UI. • style_header (record) - CSS styles to be applied to each individual header cell. That is, unlike `style_cell`, it excludes the `data` and filter cells. • style_cell_conditional (list with values of type: record with the field: 'if: record with the fields: 'column_id: string | list with values of type: string (optional)', 'column_type: value equal to: 'any', 'numeric', 'text', 'datetime' (optional)' (optional)'; default []) - Conditional CSS styles for the cells. This can be used to apply styles to cells on a per-column basis. • style_data_conditional (list with values of type: record with the field: 'if: record with the fields: 'column_id: string | list with values of type: string (optional)', 'column_type: value equal to: 'any', 'numeric', 'text', 'datetime' (optional)', 'filter_query: string (optional)', 'state: value equal to: 'active', 'selected' (optional)', 'row_index: number | value equal to: 'odd', 'even' | list with values of type: number (optional)', 'column_editable: boolean (optional)' (optional)'; default []) - Conditional CSS styles for the data cells. This can be used to apply styles to data cells on a per-column basis. • style_filter_conditional (list with values of type: record with the field: 'if: record with the fields: 'column_id: string | list with values of type: string (optional)', 'column_type: value equal to: 'any', 'numeric', 'text', 'datetime' (optional)', 'column_editable: boolean (optional)' (optional)'; default []) - Conditional CSS styles for the filter cells. This can be used to apply styles to filter cells on a per-column basis. • style_header_conditional (list with values of type: record with the field: 'if: record with the fields: 'column_id: string | list with values of type: string (optional)', 'column_type: value equal to: 'any', 'numeric', 'text', 'datetime' (optional)', 'header_index: number | list with values of type: number | value equal to: 'odd', 'even' (optional)', 'column_editable: boolean (optional)' (optional)'; default []) - Conditional CSS styles for the header cells. This can be used to apply styles to header cells on a per-column basis. • virtualization (boolean; default false) - This property tells the table to use virtualization when rendering. Assumptions are that: the width of the columns is fixed; the height of the rows is always the same; and runtime styling changes will not affect width and height vs. first rendering • derived_filter_query_structure (record) - This property represents the current structure of `filter_query` as a tree structure. Each node of the query structure has: type (string; required): 'open-block', 'logical-operator', 'relational-operator', 'unary-operator', or 'expression'; subType (string; optional): 'open-block': '()', 'logical-operator': '&&', '||', 'relational-operator': '=', '>=', '>', '<=', '<', '!=', 'contains', 'unary-operator': '!', 'is bool', 'is even', 'is nil', 'is num', 'is object', 'is odd', 'is prime', 'is str', 'expression': 'value', 'field'; value (any): 'expression, value': passed value, 'expression, field': the field/prop name. block (nested query structure; optional). left (nested query structure; optional). right (nested query structure; optional).

This property will be updated on paging, sorting, and filtering. • derived_viewport_indices (list with values of type: number; default []) - `derived_viewport_indices` indicates the order in which the original rows appear after being filtered, sorted, and/or paged. `derived_viewport_indices` contains indices for the current page, while `derived_virtual_indices` contains indices across all pages. • derived_viewport_row_ids (list with values of type: string | number; default []) - `derived_viewport_row_ids` lists row IDs in the order they appear after being filtered, sorted, and/or paged. `derived_viewport_row_ids` contains IDs for the current page, while `derived_virtual_row_ids` contains IDs across all pages. • derived_viewport_selected_columns (list with values of type: string) - `derived_viewport_selected_columns` contains the ids of the `selected_columns` that are not currently hidden. • derived_viewport_selected_rows (list with values of type: number; default []) - `derived_viewport_selected_rows` represents the indices of the `selected_rows` from the perspective of the `derived_viewport_indices`. • derived_viewport_selected_row_ids (list with values of type: string | number; default []) - `derived_viewport_selected_row_ids` represents the IDs of the `selected_rows` on the currently visible page. • derived_virtual_data (list with values of type: record; default []) - This property represents the visible state of `data` across all pages after the front-end sorting and filtering as been applied. • derived_virtual_indices (list with values of type: number; default []) - `derived_virtual_indices` indicates the order in which the original rows appear after being filtered and sorted. `derived_viewport_indices` contains indices for the current page, while `derived_virtual_indices` contains indices across all pages. • derived_virtual_row_ids (list with values of type: string | number; default []) - `derived_virtual_row_ids` indicates the row IDs in the order in which they appear after being filtered and sorted. `derived_viewport_row_ids` contains IDs for the current page, while `derived_virtual_row_ids` contains IDs across all pages. • derived_virtual_selected_rows (list with values of type: number; default []) - `derived_virtual_selected_rows` represents the indices of the `selected_rows` from the perspective of the `derived_virtual_indices`. • derived_virtual_selected_row_ids (list with values of type: string | number; default []) - `derived_virtual_selected_row_ids` represents the IDs of the `selected_rows` as they appear after filtering and sorting, across all pages. • loading_state (record with the fields: 'is_loading: boolean (optional)', 'prop_name: string (optional)', 'component_name: string (optional)') - Object that holds the loading state object coming from dash-renderer • persistence (boolean | string | number) - Used to allow user interactions in this component to be persisted when the component - or the page - is refreshed. If `persisted` is truthy and hasn't changed from its previous value, any `persisted_props` that the user has changed while using the app will keep those changes, as long as the new prop value also matches what was given originally. Used in conjunction with `persistence_type` and `persisted_props`. • persisted_props (list with values of type: value equal to: 'columns_name', 'data', 'filter_query', 'hidden_columns', 'selected_columns', 'selected_rows', 'sort_by'; default [ 'columns_name', 'filter_query', 'hidden_columns', 'selected_columns', 'selected_rows', 'sort_by' ]) - Properties whose user interactions will persist after refreshing the component or the page. • persistence_type (value equal to: 'local', 'session', 'memory'; default local) - Where persisted user changes will be stored: memory: only kept in memory, reset on page refresh. local: window.localStorage, data is kept after the browser quit. session: window.sessionStorage, data is cleared once the browser quit.
