Svelte table state

Before starting, run intent load @tanstack/table-core#table-state for shared ownership, initialization, updates, and resets.

Read reactive state

In Svelte 5, table.atoms.<slice>.get(), table.store.get(), and Table API reads track dependencies inside templates, $derived, $derived.by, or $effect. Outside those contexts they return snapshots. Prefer a slice read; a whole-store read reruns for every registered state change.

createTable and createAppTable take only options. There is no selected table.state, subscribeTable, or SubscribeSource. Use native $derived projections.

Control a slice

Keep features and columns stable. Expose changing data and controlled runes through getters, and resolve both forms of Updater:

<script lang="ts">
  import {
    createTable,
    rowPaginationFeature,
    tableFeatures,
    type PaginationState,
  } from '@tanstack/svelte-table'

  const features = tableFeatures({ rowPaginationFeature })
  const columns = [{ accessorKey: 'name' }]
  let data = $state([{ name: 'Ada' }])
  let pagination = $state<PaginationState>({ pageIndex: 0, pageSize: 20 })
  const table = createTable({
    features,
    columns,
    get data() {
      return data
    },
    state: {
      get pagination() {
        return pagination
      },
    },
    onPaginationChange: (next) => {
      pagination = typeof next === 'function' ? next(pagination) : next
    },
  })
  const pageSize = $derived(table.atoms.pagination.get().pageSize)
</script>

<button onclick={() => table.setPageSize(50)}>{pageSize} rows per page</button>

createTableState provides an updater-compatible getter/setter pair when repeating this wiring. For raw external atoms consumed outside table UI, use useSelector from @tanstack/svelte-store; table UI uses the rune-aware table.atoms wrappers.

For createTableState, external atoms, broad invalidation, or a page index overwritten by automatic reset, read reactivity details. For changes to pagination processing or reset policy, run intent load @tanstack/table-core#table-features and read its pagination reference.

API discovery

Inspect node_modules/@tanstack/svelte-table/dist/createTable.svelte.d.ts, createTableState.svelte.d.ts, and createTableHook.svelte.d.ts for the installed contracts.
