table

Aggregate TanStack Table columns independently of grouping, including grand totals, caller-selected row totals, multiple keyed aggregations, custom context-based definitions, grouped merges, manual values, and worker constraints.

Diagnose missing TanStack Table v9 exports, options, state slices, and instance methods. Load before inventing an API when code sees a type error, undefined feature method, absent object key, adapter mismatch, or v8-shaped example.

Select, add, and subtract rectangular cell ranges with cellSelectionFeature: ordered include/exclude operations keyed by row and column id, modifier dragging, final positive bounds, selection edges, render-order resolution under pinning, and autoResetCellSelection. Load for spreadsheet-style selection, “select all except” behavior, unexpected range changes after sorting or reordering, drag performance, or copy-to-clipboard.

Merge adjacent body cells with cellSpanningFeature: value-based rowSpan opt-in per column via spanRows, per-row colSpan via spanColumns, and the covered-cell convention where a span of 0 means skip the cell. Load for merged data grids, spans that disappear after sorting or paginating, ragged table rows, or a cell that unexpectedly merges down the whole tbody.

Choose client or server ownership for filtering, grouping, sorting, expanding, and pagination in TanStack Table v9. Load for manual* flags, mixed pipelines, server counts, or deciding which dataset each row-model stage receives.

Build faceted filter UIs with columnFacetingFeature, facetedRowModel, facetedUniqueValues, and facetedMinMaxValues. Load for facet counts, numeric ranges, own-filter exclusion, or server-page facet completeness.

Filter columns with columnFilteringFeature, filteredRowModel, filterFns, filterMeta, nested-row direction, and manualFiltering. Load for accessor compatibility, controlled filter updaters, fuzzy metadata, or client/server ownership.

Control TanStack Table v9 leaf columnOrder with stable IDs while accounting for pinning regions, visibility, and groupedColumnMode precedence. Load for drag-and-drop columns or rendered order that differs from state.

Pin columns into logical start, center, and end regions with columnPinningFeature and renderer-owned sticky CSS. Load for RTL offsets, z-index, backgrounds, overflow, widths, gaps, or overlaps.

Wire columnResizingFeature, header.getResizeHandler, resize mode and direction, pointer or touch events, and performant CSS-variable updates. Load when resize state changes but widths do not, or large tables resize slowly.

Use columnSizingFeature numeric size, minSize, maxSize, getSize, getStart, getAfter, and total-size APIs in table, grid, or flex CSS. Load for auto or percentage misconceptions and sizing/pinning layout mismatch.

Hide columns with columnVisibilityFeature while rendering visibility-aware header, column, and cell collections. Load when hidden columns remain in the DOM, false-versus-absent state is confused, or enableHiding is misunderstood.

Use TanStack Table v9 as a headless data-grid state and row-processing engine. Load for first-table architecture, stable data and columns, row numbering with getDisplayIndex, semantic rendering, framework adapter choice, or deciding what Table owns versus the renderer.

Share Alpine tableFeatures, defaults, createAppTable, and createAppColumnHelper with createTableHook. Load when multiple Alpine tables repeat infrastructure; unlike JSX adapters, Alpine has no registered table/cell/header component or context registry.

Create a reusable Lit useAppTable/createAppColumnHelper layer with host-backed controllers, shared features/defaults, typed cell/header renderers, App wrappers, and useTableContext for custom-element controls. Load when multiple Lit tables share infrastructure or prop drilling obscures table context.

Define a Svelte createAppTable/createAppColumnHelper using the adapter's rune-capable createTableHook implementation, shared features/defaults, reactive per-table getters, optional App component registries, and typed table/cell/header context hooks.

Share TanStack Ember Table v9 features, row-model slots, defaults, and inferred column helpers with createTableHook, createAppTable, createAppColumnHelper, and appFeatures. Load for recurring Ember table conventions, per-table overrides, or confusion with component/context registries from other adapters.

Create reusable Solid table infrastructure with createTableHook, createAppTable, createAppColumnHelper, shared features/defaults, component registries, App wrappers, and typed context hooks. Load for recurring app conventions, reactive per-table getters, or prop drilling.

Create a reusable Vue useAppTable/createAppColumnHelper with shared features/defaults, reactive per-table options, optional component registries, dynamic App wrappers, typed context hooks, and explicit types that break circular inference.

Create reusable Octane table infrastructure with createTableHook, useAppTable, createAppColumnHelper, registered components, stable App wrappers, and typed context hooks. Load for recurring conventions, scoped contexts, or prop drilling.
