react-table vs react-table-6: Architecture, API, and Maintenance

Both react-table and react-table-6 are popular solutions for building complex tables in React applications, but they belong to different eras of React development. react-table (v7+) embraces the modern hooks ecosystem, while react-table-6 relies on older component patterns. Understanding these differences is critical for architectural decisions, especially regarding long-term maintainability and flexibility.

🏗️ Core API: Hooks vs Components

react-table is built entirely around React hooks.

• You call useTable (and other plugin hooks) to get table state and helper functions.
• You are responsible for rendering the actual HTML elements (<table>, <thead>, etc.).
• This makes it "headless" — it handles logic, you handle UI.

// react-table (v7): Hook-based API
import { useTable } from 'react-table';

function Table({ columns, data }) {
  const {
    getTableProps,
    getTableBodyProps,
    headerGroups,
    rows,
    prepareRow,
  } = useTable({ columns, data });

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th {...column.getHeaderProps()}>
                {column.render('Header')}
              </th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody {...getTableBodyProps()}>
        {rows.map(row => {
          prepareRow(row);
          return (
            <tr {...row.getRowProps()}>
              {row.cells.map(cell => (
                <td {...cell.getCellProps()}>
                  {cell.render('Cell')}
                </td>
              ))}
            </tr>
          );
        })}
      </tbody>
    </table>
  );
}

react-table-6 uses a monolithic component approach.

• You pass data and configuration as props to a <ReactTable /> component.
• The library renders the DOM structure for you (usually <div> based by default).
• Customization happens via render props or CSS classes.

// react-table-6: Component-based API
import ReactTable from 'react-table-6';

function Table({ columns, data }) {
  return (
    <ReactTable
      data={data}
      columns={columns}
      defaultPageSize={10}
      className="-striped -highlight"
    />
  );
}

🎨 Rendering Control: Semantic HTML vs Default Structure

react-table forces you to build the markup.

• You decide if it is a <table>, a grid of <div>s, or a virtualized list.
• Better for accessibility (a11y) because you can ensure semantic tags are used.
• Requires more boilerplate code initially.

// react-table: You control the semantic tags
return (
  <table {...getTableProps()}>
    <thead>...</thead>
    <tbody>...</tbody>
  </table>
);

react-table-6 provides a default DOM structure.

• Historically used nested <div>s instead of semantic <table> tags by default.
• Easier to get started quickly but harder to make fully accessible.
• Styling relies on overriding specific library-generated class names.

// react-table-6: Library controls the tags
// Renders internal div structure like:
// <div class="rt-table">
//   <div class="rt-thead">...</div>
//   <div class="rt-tbody">...</div>
// </div>

🔌 Features: Plugin Hooks vs Built-in Props

react-table splits features into separate hooks.

• Sorting, pagination, and filtering are optional plugins (e.g., useSortBy, usePagination).
• You only bundle what you use, keeping potential tree-shaking benefits.
• State for each feature is exposed and can be controlled externally.

// react-table: Composable hooks
import { useTable, useSortBy, usePagination } from 'react-table';

const {
  state: { sortBy },
  setSortBy,
  // ... pagination props
} = useTable(
  { columns, data },
  useSortBy,
  usePagination
);

react-table-6 bundles features into the main component.

• Features are toggled via boolean props (e.g., sortable, pagination).
• Less granular control over feature state.
• Easier configuration for standard use cases but rigid for complex needs.

// react-table-6: Built-in props
<ReactTable
  data={data}
  columns={columns}
  sortable={true}
  pagination={true}
  onSortedChange={newSort => { /* handle sort */ }}
/>

🔄 State Management: Controlled vs Semi-Controlled

react-table is designed to be fully controlled.

• You can lift table state (sorting, page index, filters) to your own state management.
• Essential for server-side pagination or syncing table state with URL query params.
• Requires more setup but offers maximum power.

// react-table: Controlled state
const [state, setState] = React.useState({
  pageIndex: 0,
  pageSize: 10,
});

const {
  state: { pageIndex },
  gotoPage,
} = useTable({
  columns,
  data,
  state,
  onPageChange: page => setState({ ...state, pageIndex: page })
});

react-table-6 manages state internally by default.

• You can control it via props like page and onPageChange, but it's less consistent.
• Often leads to "fighting the library" when trying to sync external state.
• Simpler for client-side only tables where internal state is fine.

// react-table-6: Internal state default
<ReactTable
  data={data}
  page={pageIndex}
  onPageChange={page => setPageIndex(page)}
  // Internal state handles the rest unless overridden
/>

🛠️ Maintenance and Future Proofing

react-table (v7) is the stable predecessor to the TanStack ecosystem.

• Actively maintained but the team now focuses on @tanstack/react-table (v8).
• v7 is still safe for production but consider v8 for new greenfield projects.
• Large community and extensive plugin ecosystem.

react-table-6 is deprecated and archived.

• No new features or security updates.
• Incompatible with React 18+ strict mode in some edge cases.
• Should be migrated away from in any long-term project.

📊 Summary: Key Differences

💡 The Big Picture

react-table is the professional choice for modern React development. It treats the table as a collection of logic hooks that you compose into your own UI. This approach aligns with how modern React libraries are built (like Headless UI or Radix). It requires more initial code but pays off in flexibility and maintainability.

react-table-6 is a relic of an earlier React era. While it was revolutionary at the time, its component-heavy API and internal state management make it difficult to integrate with modern patterns like server components or complex state synchronization.

Final Thought: If you are touching react-table-6 today, plan a migration path to react-table (v7) or @tanstack/react-table (v8). The hook-based architecture is not just a trend; it provides the necessary leverage to build complex, accessible, and performant data grids that scale with your application.
