React Final Table

A headless UI component libray for managing complex table state in React.

Inspired by react-table but with Typescript support built in and a simpler API.

Features

• Type safe
• Global row filtering
• Row selection
• Custom column rendering
• Column sorting
• Data memoization for performance
• Zero dependencies

Motivation

While there is an abundance of table libraries out there to help with sorting, filtering, pagination, and more, most are opinionated about the user interface. Opinionated UIs can seem nice at first, but they quickly become limiting. To embrace the Unix philosphy of separation of concerns, the interface should be separate from the engine (from The Art of Unix Programming).

This is a minimal, type-safe, headless UI component library that you can plugin to whatever frontend you're using, as long as you're using React 16 and Hooks. You are then free to style your table any way you want while using React Final Table to manage complex state changes.

Install

npm install react-final-table

Hooks

useTable

This is the main hook exposed by the library and should be your entrypoint for any table functionality. Only columns and data are required as arguments:

const {
  headers,
  rows,
  selectRow,
  selectedRows
} = useTable(columns, data, {
  selectable?: boolean,
  filter?: (rows: RowType<T>[]) => RowType<T>[],
});

Basic example

import { useTable } from 'react-final-table';

const columns = [
  {
    name: 'firstName',
    label: 'First Name',
    render: ({ value }) => <h1>{value}</h1>, // optional
  },
  {
    name: 'lastName',
    label: 'Last Name',
  },
];

const data = [
  {
    firstName: 'Frodo',
    lastName: 'Baggins',
  },
  {
    firstName: 'Samwise',
    lastName: 'Gamgee',
  },
];

const MyTable = () => {
  const { headers, rows } = useTable(columns, data);

  return (
    <table>
      <thead>
        <tr>
          {headers.map((header, idx) => (
            <th key={idx}>{header.label}</th>
          ))}
        </tr>
      </thead>
      <tbody>
        {rows.map((row, idx) => (
          <tr key={idx}>
            {row.cells.map((cell, idx) => (
              <td key={idx}>{cell.render()}</td>
            ))}
          </tr>
        ))}
      </tbody>
    </table>
  );
};

Advanced Example

import React, { useMemo } from 'react';
import { useTable } from 'react-final-table';

const columns = [
  { name: 'id', hidden: true },
  {
    name: 'first_name',
    label: 'First Name',
    render: ({ value }: { value: string }) => <span>Sir {value}</span>,
  },
  {
    name: 'last_name',
    label: 'Last Name',
  },
];

const data = [
  {
    id: 1,
    first_name: 'Frodo',
    last_name: 'Baggins',
  },
  {
    id: 2,
    first_name: 'Samwise',
    last_name: 'Gamgee',
  },
];

function App() {
  const memoColumns = useMemo(() => columns, []);
  const memoData = useMemo(() => data, []);

  const { headers, rows, selectRow, selectedRows } = useTable(
    memoColumns,
    memoData,
    {
      selectable: true,
    }
  );

  return (
    <>
      <table>
        <thead>
          <tr>
            <th></th>
            {headers.map((header, idx) => (
              <th key={idx}>{header.label}</th>
            ))}
          </tr>
        </thead>
        <tbody>
          {rows.map((row, idx) => (
            <tr key={idx}>
              <td>
                <input
                  type="checkbox"
                  onChange={e => {
                    selectRow(row.id);
                  }}
                />
              </td>
              {row.cells.map((cell, idx) => (
                <td key={idx}>{cell.render()}</td>
              ))}
            </tr>
          ))}
        </tbody>
      </table>
      <pre>
        <code>{JSON.stringify(selectedRows, null, 2)}</code>
      </pre>
    </>
  );
}

export default App;
