Tanstack Octane Table Create Table Hook

This skill builds on @tanstack/table-core#core, getting-started, and table-state. Use the app hook for repeated conventions; keep a one-off table on useTable.

Setup

import {
  createTableHook,
  rowSelectionFeature,
  tableFeatures,
} from '@tanstack/octane-table'

export const { createAppColumnHelper, useAppTable, useTableContext } =
  createTableHook({
    features: tableFeatures({ rowSelectionFeature }),
    getRowId: (row: { id: string }) => row.id,
  })

Create the factory at module scope. Its wrappers have stable identities and read the latest table facade without remounting their child subtrees.

Core Patterns

Use the factory-bound helper

type Person = { id: string; name: string }
const helper = createAppColumnHelper<Person>()
const columns = helper.columns([helper.accessor('name', { header: 'Name' })])

Consume typed context under its wrapper

function RowCount() @{
  const table = useTableContext()
  <output>{String(table.getRowModel().rows.length)}</output>
}

function Grid() @{
  const table = useAppTable({ data, columns })
  <table.AppTable><RowCount /></table.AppTable>
}

AppTable takes static children without a selector. Use function children when a selector supplies their value:

<table.AppTable selector={(state) => state.rowSelection}>
  {(rowSelection) => <output>{String(Object.keys(rowSelection).length)}</output>}
</table.AppTable>

Render AppTable, AppCell, AppHeader, AppFooter, and registered components with JSX. The wrappers establish context and independent Octane scopes.

Isolate genuinely nested table setups

Default contexts are module-scoped and HMR-stable. Sibling tables are isolated by their providers, but nested factories can resolve a consumer to the inner provider. Create fresh contexts for distinct nested setups:

import {
  createTableHook,
  createTableHookContexts,
  rowSelectionFeature,
  tableFeatures,
} from '@tanstack/octane-table'

const features = tableFeatures({ rowSelectionFeature })
const { tableContext, cellContext, headerContext } =
  createTableHookContexts<typeof features>()

export const app = createTableHook({
  features,
  tableContext,
  cellContext,
  headerContext,
})

Prefer hooks returned by createTableHook because their types include registered component maps.

Common Mistakes

MEDIUM Abstracting a single table

Wrong:

const app = createTableHook({ features: tableFeatures({}) })

Correct:

const table = useTable({ features, columns, data })

The factory is valuable when it centralizes repeated policy, registered renderers, or typed context—not merely as another constructor name.

HIGH Reading outside the matching provider

Wrong:

function Grid() @{
  <RowCount />
}

Correct:

function Grid() @{
  const table = useAppTable({ data, columns })
  <table.AppTable><RowCount /></table.AppTable>
}

Factory context hooks throw actionable errors when the matching AppTable, AppCell, or AppHeader provider is missing.

HIGH Recreating the factory during render

Wrong:

function Grid() @{
  const app = createTableHook({ features })
  const table = app.useAppTable({ data, columns })
  <table.AppTable />
}

Correct:

const app = createTableHook({ features })

function Grid() @{
  const table = app.useAppTable({ data, columns })
  <table.AppTable />
}

A factory created during render makes hook configuration, wrappers, contexts, and registered component identities unstable.
