## DataTable A data driven table. [![](https://cdn-images-1.medium.com/fit/c/120/120/1*TD1P0HtIH9zF0UEH28zYtw.png)](https://storybook.grommet.io/?selectedKind=DataTable&full=0&addons=0&stories=1&panelRight=0) [![](https://codesandbox.io/static/img/play-codesandbox.svg)](https://codesandbox.io/s/github/grommet/grommet-sandbox?initialpath=datatable&module=%2Fsrc%2FDataTable.js) ## Usage ```javascript import { DataTable } from 'grommet'; <DataTable /> ``` ## Properties **a11yTitle** Custom title to be used by screen readers. ``` string ``` **alignSelf** How to align along the cross axis when contained in a Box or along the column axis when contained in a Grid. ``` start center end stretch ``` **gridArea** The name of the area to place this inside a parent Grid. ``` string ``` **margin** The amount of margin around the component. An object can be specified to distinguish horizontal margin, vertical margin, and margin on a particular side. ``` none xxsmall xsmall small medium large xlarge { bottom: xxsmall xsmall small medium large xlarge string, horizontal: xxsmall xsmall small medium large xlarge string, left: xxsmall xsmall small medium large xlarge string, right: xxsmall xsmall small medium large xlarge string, top: xxsmall xsmall small medium large xlarge string, vertical: xxsmall xsmall small medium large xlarge string } string ``` **columns** A description of the data. The order controls the column order. 'property' indicates which property in the data objects to associate the column with. 'header' indicates what to display in the column header. 'render' allows for custom rendering of body cells. Use 'render' for custom formatting for things like currency and date or to display rich content like Meters. 'align' indicates how the cells in the column are aligned. 'aggregate' indicates how the data in the column should be aggregated. This only applies to a footer or groupBy context. 'footer' indicates what should be shown in the footer for the column. 'search' indicates whether a search filter should be made available for the column. 'primary' indicates that this property should be used as the unique identifier, which gives the cell 'row' scope for accessibility. If 'primary' is not used for any column, and 'primaryKey' isn't specified either, then the first column will be used. Defaults to `[]`. ``` [{ align: center start end, aggregate: avg max min sum, footer: node { aggregate: boolean }, header: string node { aggregate: boolean }, primary: boolean, property: string, render: function, search: boolean, sortable: boolean }] ``` **data** Array of data objects. Defaults to `[]`. ``` [{ }] ``` **groupBy** Property to group data by. ``` string ``` **onMore** Use this to indicate that 'data' doesn't contain all that it could. It will be called when all of the data rows have been rendered. This might be used when the total number of items that could be retrieved is more than you'd want to load into the browser. 'onMore' allows you to lazily fetch more from the server only when needed. This cannot be combined with properties that expect all data to be present in the browser, such as columns.search, sortable, groupBy, or columns.aggregate. ``` function ``` **onSearch** When supplied, and when at least one column has 'search' enabled, this function will be called with an object with keys for property names and values which are the search text strings. This is typically employed so a back-end can be used to search through the data. ``` function ``` **primaryKey** When supplied, indicates the property for a data object to use to get a unique identifier. See also the 'columns.primary' description. Use this property when the columns approach will not work for your data set. ``` string ``` **resizeable** Whether to allow the user to resize column widths. ``` boolean ``` **size** The height of the table body. If set, the table body will have a fixed height and the rows will be scrollable within it. In order to preserve header and footer cell alignment, all cells will have the same width. This cannot be used in combination with 'resizeable'. ``` small medium large xlarge string ``` **sortable** Whether to allow the user to sort columns. ``` boolean ``` ## Intrinsic element ``` table ```
