TanStack Table

Use this skill when work touches TanStack Table v9 beta, especially @tanstack/react-table@beta, table feature composition, complex data-grid behavior, or migration from v8 APIs.

Workflow

  1. Confirm the local version and target API before changing code:
    • @tanstack/react-table, @tanstack/table-core, optional devtools, optional @tanstack/react-store, optional @tanstack/react-virtual, and React version.
    • Whether the app is intentionally on v9 beta. The latest dist-tag is still v8; v9 requires the @beta tag.
    • Current table creation style: useTable, createTableHook, or temporary useLegacyTable.
    • Which features are registered in tableFeatures() and which row model factories are actually needed.
  2. Refresh current docs for beta churn, migrations, new feature APIs, or package mismatches. Start from source-map.md.
  3. For installation, core setup, columns, rendering, and row models, use setup-core.md.
  4. For v8-to-v9 migrations, useLegacyTable, state ownership, external atoms, selectors, and React Compiler concerns, use state-and-migration.md.
  5. For sorting, filtering, faceting, pagination, selection, pinning, sizing, grouping, and expanding, use features.md.
  6. For server-side patterns, TanStack Query, virtualization, devtools, worker row models, performance, accessibility, and testing, use production-patterns.md.

Implementation Judgment

  • Treat v9 as beta. Verify names and options before relying on memory, especially around row model slots, devtools, and experimental worker row models.
  • Prefer useTable plus explicit tableFeatures() for one-off tables. Use createTableHook when multiple tables share features, defaults, or standardized components.
  • Register only the features the table needs. The core row model is automatic; client-side filtering, sorting, grouping, expanding, faceting, and pagination need matching row model factories.
  • Keep data, columns, and reusable column helpers stable across renders.
  • Do not destructure methods from row, cell, column, or header instances. Call them on the instance.
  • Use table.FlexRender or the v9 FlexRender component for cells and headers.
  • Prefer external atoms for state that powers server queries, persistence, or cross-component UI. The classic state plus onXChange pattern remains useful for simple migration work.
  • Use manualSorting, manualFiltering, manualPagination, and manualGrouping when the server already returns processed data. Keep all table operations consistent at the same data scope.
  • Treat useLegacyTable as a temporary migration bridge only. It bundles all features, keeps full-state subscriptions, and does not support the main v9 composability benefits.

Verification

Prefer the repo's existing checks. For meaningful TanStack Table changes, include the relevant subset:

  • Package/version check proving v9 beta APIs are available when used.
  • Typecheck for feature registration, column definitions, state slices, and row model slots.
  • Focused interaction tests for sorting, filtering, pagination, selection, expansion, pinning, resizing, and server-query integration.
  • Browser smoke for rendered markup, keyboard/focus behavior, sticky or virtualized layouts, and resize/scroll performance.
  • Production build or profiling pass for large tables, virtualization, or column resizing changes.
