AG Grid React: Build fast, interactive React data tables

Why AG Grid in React — when and why to pick it

AG Grid is a purpose-built React data grid library that scales from simple tables to complex, spreadsheet-like UIs. If your app needs robust client- and server-side filtering, multi-column sorting, column grouping, pivoting, aggregation or inline cell editing (think spreadsheets in the browser), AG Grid React is purpose-made for that workload.

Compared with lightweight React table components, AG Grid trades some initial complexity for features and performance. It provides optimized row virtualization, dozens of column and cell customization hooks, and production features such as row models (client, infinite, server-side) that reduce the mental overhead when datasets grow beyond tens of thousands of rows.

Pick AG Grid React for enterprise apps, dashboards, and data-heavy tools. For tiny static tables or simple list rendering you might prefer a minimal React table component, but where scalability, interactivity, and built-in features matter, AG Grid wins.

AG Grid React setup & installation

Start by installing the official packages. The core grid comes from ag-grid-community (or the enterprise package if you need enterprise-only features). For React bindings, install ag-grid-react. Use npm or yarn in your project root:

npm install --save ag-grid-community ag-grid-react
# or
yarn add ag-grid-community ag-grid-react

After installation import the styles and the grid component in your React app. AG Grid ships with several themes; the CSS import will look like this:

import 'ag-grid-community/styles/ag-grid.css';
import 'ag-grid-community/styles/ag-theme-alpine.css';
import { AgGridReact } from 'ag-grid-react';

AG Grid React setup includes column definitions, row data, and optional grid options. Initialize columnDefs and rowData in state or props, and pass them to the AgGridReact component. This structure keeps your grid declarative and reactive to prop/state changes.

Core features: filtering, sorting, pagination, and cell editing

Filtering and sorting are first-class capabilities. Column definitions accept filter and sortable flags and AG Grid provides many built-in filters (text, number, date, set) plus custom filter components. Sorting supports multi-column direction and programmatic control through the grid API.

Pagination in AG Grid is flexible. For client-side datasets you can enable built-in pagination with a page size. For larger datasets, choose infinite scrolling or server-side pagination (server-side row model) to fetch data chunks on demand. Controls and UI are customizable so you can match your UX spec.

Cell editing supports inline editing, cell renderers, and custom editors. AG Grid can handle validation, edit commit/cancel events, and complex cell types (selects, date pickers). Combine cell renderers and editors to build spreadsheet-like behaviors such as formula cells or conditional formatting.

Advanced patterns & customization

For very large datasets, enable row virtualization and pick the appropriate row model. The client-side model is simple and fast for moderate datasets. For streaming or paged data, the infinite or server-side row models reduce memory and network load by loading only visible rows.

Customize cells with cellRenderer and cellEditor components. In React you can pass functional components or class components to render complex UI inside a cell. Use valueFormatter and valueGetter for transformation and derived columns to keep data normalization separate from presentation.

AG Grid exposes a rich API for column state (resize, move, hide), sorting, filtering, and exporting. Combine the grid API with React refs to call imperative methods (api.exportDataAsCsv(), api.refreshCells(), or api.setFilterModel()). This is ideal for building advanced toolbars and user controls.

Performance and best practices

Performance targets: minimize re-renders by keeping columnDefs and gridOptions stable (useMemo/useCallback). Avoid recreating objects on each render. AG Grid’s change detection favors immutable row data updates with deltaRowDataMode when possible.

Choose the right row model: client-side for small/medium data, infinite or server-side for tens/hundreds of thousands of rows. Server-side row model supports partial aggregation and group operations on the server, reducing the client CPU and memory footprint.

Use virtualization and pagination to limit DOM nodes. Keep heavy logic outside render loops and use cell renderers for complex UI only when necessary. When using custom components, clean up subscriptions in componentWillUnmount/useEffect cleanup to prevent memory leaks.

AG Grid React example — minimal, functional

The following example shows a compact React component using AG Grid with filtering, sorting, pagination, and cell editing enabled. It demonstrates a realistic setup without enterprise features. Paste into a create-react-app and adapt columnDefs and rowData for your data model.

import React, { useState, useMemo } from 'react';
import { AgGridReact } from 'ag-grid-react';
import 'ag-grid-community/styles/ag-grid.css';
import 'ag-grid-community/styles/ag-theme-alpine.css';

export default function MyGrid() {
  const [rowData] = useState([
    { id: 1, name: 'Alice', age: 30 },
    { id: 2, name: 'Bob', age: 24 },
    { id: 3, name: 'Carol', age: 41 },
  ]);

  const columnDefs = useMemo(() => [
    { field: 'id', sortable: true, filter: 'agNumberColumnFilter' },
    { field: 'name', sortable: true, filter: 'agTextColumnFilter', editable: true },
    { field: 'age', sortable: true, filter: 'agNumberColumnFilter', editable: true },
  ], []);

  return (
    <div className="ag-theme-alpine" style={{height:400, width:'100%'}}>
      <AgGridReact
        rowData={rowData}
        columnDefs={columnDefs}
        pagination={true}
        paginationPageSize={10}
        defaultColDef={{ resizable: true }}
      />
    </div>
  );
}

This example gives you a working React data table with sorting, filtering and inline editing. Expand with cell renderers, custom editors or server-side pagination depending on scale and UX requirements.
