> Important

> rolldown-vite by default uses lightningcss to minify css which has a bug minifying light-dark syntax. You can switch to esbuild as a workaround

``ts
build: {
....,
cssMinify: 'esbuild'
}
`

Installation

Install react-data-grid using your favorite package manager:

`sh
npm i react-data-grid
`

`sh
pnpm add react-data-grid
`

`sh
yarn add react-data-grid
`

`sh
bun add react-data-grid
`

Additionally, import the default styles in your application:

`tsx
import 'react-data-grid/lib/styles.css';
`

react-data-grid is published as ECMAScript modules for evergreen browsers, bundlers, and server-side rendering.

Getting started

Here is a basic example of how to use react-data-grid in your React application:

`tsx
import 'react-data-grid/lib/styles.css';

import { DataGrid, type Column } from 'react-data-grid';

interface Row {
id: number;
title: string;
}

const columns: readonly Column[] = [
{ key: 'id', name: 'ID' },
{ key: 'title', name: 'Title' }
];

const rows: readonly Row[] = [
{ id: 0, title: 'Example' },
{ id: 1, title: 'Demo' }
];

function App() {
return ;
}
`

Theming

Set --rdg-color-scheme: light/dark at the :root to control the color theme. The light or dark themes can be enforced using the rdg-light or rdg-dark classes.

API Reference

####

##### DataGridProps

###### columns: readonly Column[]

An array of column definitions. Each column should have a key and name. See the Column type for all available options.

:warning: Performance: Passing a new columns array will trigger a re-render and recalculation for the entire grid. Always memoize this prop using useMemo or define it outside the component to avoid unnecessary re-renders.

###### rows: readonly R[]

An array of rows, the rows data can be of any type.

:bulb: Performance: The grid is optimized for efficient rendering:

- Virtualization: Only visible rows are rendered in the DOM
- Individual row updates: Row components are memoized, so updating a single row object will only re-render that specific row, not all rows
- Array reference matters: Changing the array reference itself (e.g., setRows([...rows])) triggers viewport and layout recalculations, even if the row objects are unchanged
- Best practice: When updating rows, create a new array but reuse unchanged row objects. For example:

`tsx
// ✅ Good: Only changed row is re-rendered
setRows(rows.map((row, idx) => (idx === targetIdx ? { ...row, updated: true } : row)));

// ❌ Avoid: Creates new references for all rows, causing all visible rows to re-render
setRows(rows.map((row) => ({ ...row })));
`

###### topSummaryRows?: Maybe

Rows pinned at the top of the grid for summary purposes.

###### bottomSummaryRows?: Maybe

Rows pinned at the bottom of the grid for summary purposes.

###### rowKeyGetter?: Maybe<(row: R) => K>

Function to return a unique key/identifier for each row. rowKeyGetter is required for row selection to work.

`tsx
import { DataGrid } from 'react-data-grid';

interface Row {
id: number;
name: string;
}

function rowKeyGetter(row: Row) {
return row.id;
}

function MyGrid() {
return ;
}
`

:bulb: While optional, setting this prop is recommended for optimal performance as the returned value is used to set the key prop on the row elements.

:warning: Performance: Define this function outside your component or memoize it with useCallback to prevent unnecessary re-renders.

###### onRowsChange?: Maybe<(rows: R[], data: RowsChangeData) => void>

Callback triggered when rows are changed.

The first parameter is a new rows array with both the updated rows and the other untouched rows.
The second parameter is an object with an indexes array highlighting which rows have changed by their index, and the column where the change happened.

`tsx
import { useState } from 'react';
import { DataGrid } from 'react-data-grid';

function MyGrid() {
const [rows, setRows] = useState(initialRows);

return ;
}
`

###### rowHeight?: Maybe number)>

Default: 35 pixels

Height of each row in pixels. A function can be used to set different row heights.

:warning: Performance: When using a function, the height of all rows is calculated upfront on every render. For large datasets (1000+ rows), this can cause performance issues. Consider using a fixed height when possible, or memoize the rowHeight function.

###### headerRowHeight?: Maybe

Default: 35 pixels

Height of the header row in pixels.

###### summaryRowHeight?: Maybe

Default: 35 pixels

Height of each summary row in pixels.

###### columnWidths?: Maybe

A map of column widths containing both measured and resized widths. If not provided then an internal state is used.

`tsx
const [columnWidths, setColumnWidths] = useState((): ColumnWidths => new Map());

function addNewRow() {
setRows(...);
// reset column widths after adding a new row
setColumnWidths(new Map());
}

return
`

###### onColumnWidthsChange?: Maybe<(columnWidths: ColumnWidths) => void>

Callback triggered when column widths change. If not provided then an internal state is used.

###### selectedRows?: Maybe>

A set of selected row keys. rowKeyGetter is required for row selection to work.

###### isRowSelectionDisabled?: Maybe<(row: NoInfer) => boolean>

Function to determine if row selection is disabled for a specific row.

###### onSelectedRowsChange?: Maybe<(selectedRows: Set) => void>

`tsx
import { useState } from 'react';
import { DataGrid, SelectColumn } from 'react-data-grid';

const rows: readonly Rows[] = [...];

const columns: readonly Column[] = [
SelectColumn,
// other columns
];

function rowKeyGetter(row: Row) {
return row.id;
}

function isRowSelectionDisabled(row: Row) {
return !row.isActive;
}

function MyGrid() {
const [selectedRows, setSelectedRows] = useState((): ReadonlySet => new Set());

return (
rowKeyGetter={rowKeyGetter}
columns={columns}
rows={rows}
selectedRows={selectedRows}
isRowSelectionDisabled={isRowSelectionDisabled}
onSelectedRowsChange={setSelectedRows}
/>
);
}
`

###### sortColumns?: Maybe

An array of sorted columns.

###### onSortColumnsChange?: Maybe<(sortColumns: SortColumn[]) => void>

key: 'name',
name: 'Name',
sortable: true
},
// other columns
];

function MyGrid() {
const [sortColumns, setSortColumns] = useState([]);

return (
columns={columns}
rows={rows}
sortColumns={sortColumns}
onSortColumnsChange={setSortColumns}
/>
);
}
`

More than one column can be sorted via ctrl (command) + click. To disable multiple column sorting, change the onSortColumnsChange function to

`tsx
function onSortColumnsChange(sortColumns: SortColumn[]) {
setSortColumns(sortColumns.slice(-1));
}
`

###### defaultColumnOptions?: Maybe>

Default options applied to all columns.

###### 'data-testid'?: Maybe

This prop can be used to add a testid for testing. We recommend querying the grid by by its role and name.

`tsx
function MyGrid() {
return ;

});
`

####

TreeDataGrid is a component built on top of DataGrid to add hierarchical row grouping. This implements the Treegrid pattern.

How it works:

1. The groupBy prop specifies which columns should be used for grouping
2. The rowGrouper function groups rows by the specified column keys
3. Group rows are rendered with expand/collapse toggles
4. Child rows are nested under their parent groups
5. Groups can be expanded/collapsed by clicking the toggle or using keyboard navigation (←, →)

Keyboard Navigation:

- → (Right Arrow): Expand a collapsed group row when focused
- ← (Left Arrow): Collapse an expanded group row when focused, or navigate to parent group

Unsupported Props:

The following DataGrid props are not supported in TreeDataGrid:

- onFill - Drag-fill is disabled for tree grids
- isRowSelectionDisabled - Row selection disabling is not available

Caveats:

- Group columns cannot be rendered under one column
- Group columns are automatically frozen and cannot be unfrozen
- Cell copy/paste does not work on group rows

##### TreeDataGridProps

All DataGridProps are supported except those listed above, plus the following additional props:

###### groupBy: readonly string[]

Required. An array of column keys to group by. The order determines the grouping hierarchy (first key is the top level, second key is nested under the first, etc.).

`tsx
import { TreeDataGrid, type Column } from 'react-data-grid';

interface Row {
id: number;
country: string;
city: string;
name: string;
}

const columns: readonly Column[] = [
{ key: 'country', name: 'Country' },
{ key: 'city', name: 'City' },
{ key: 'name', name: 'Name' }
];

function MyGrid() {
return (
columns={columns}
rows={rows}
groupBy={['country', 'city']}
// ... other props
/>
);
}
`

###### rowGrouper: (rows: readonly R[], columnKey: string) => Record

Required. A function that groups rows by the specified column key. Returns an object where keys are the group values and values are arrays of rows belonging to that group.

`tsx
function rowGrouper(rows: Row[], columnKey: string) {
return Object.groupBy(rows, (row) => row[columnKey]);
}
`

###### expandedGroupIds: ReadonlySet

Required. A set of group IDs that are currently expanded. Group IDs are generated by groupIdGetter.

`tsx
import { useState } from 'react';
import { TreeDataGrid } from 'react-data-grid';

function MyGrid() {
const [expandedGroupIds, setExpandedGroupIds] = useState((): ReadonlySet => new Set());

return (
expandedGroupIds={expandedGroupIds}
onExpandedGroupIdsChange={setExpandedGroupIds}
// ... other props
/>
);
}
`

###### onExpandedGroupIdsChange: (expandedGroupIds: Set) => void

Required. Callback triggered when groups are expanded or collapsed.

###### groupIdGetter?: Maybe<(groupKey: string, parentId?: string) => string>

Function to generate unique IDs for group rows. If not provided, a default implementation is used that concatenates parent and group keys with __.

###### rowHeight?: Maybe) => number)>

Note: Unlike DataGrid, the rowHeight function receives RowHeightArgs which includes a type property to distinguish between regular rows and group rows:

`tsx
function getRowHeight(args: RowHeightArgs): number {
if (args.type === 'GROUP') {
return 50; // Custom height for group rows
}
return 35; // Height for regular rows
}
