table-state

Read and control TanStack Table v9 state in Vue while keeping updates synchronized with the interface. Covers reactive reads, externally controlled state, update callbacks, shared state containers, and component boundaries for rendering.

OriginalShow the original description

Read and control Table v9 state in vue. Use for tracked reads, subscriptions, controlled slices, and framework-specific reactive boundaries.

See how to install

Good for

  • Controlling pagination with Vue refs
  • Displaying table state through computed values
  • Investigating state synchronization failures
  • Sharing table state through a stable atom

Vue table state

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

Read reactive state

Vue-backed atom reads track dependencies inside templates, computed, watch, or a render boundary. const page = table.atoms.pagination.get() outside tracking captures a snapshot. Keep reactive option inputs as refs, computed values, or getters; passing .value once breaks later synchronization.

table.Subscribe is deprecated. Read table APIs or atoms directly inside templates, render functions, computed getters, or watcher sources. Use a child component when reads need a separate component render boundary.

Control a slice

Keep features and columns stable. Preserve both the reactive value and its matching callback:

import { computed, ref } from 'vue'
import {
  rowPaginationFeature,
  tableFeatures,
  useTable,
  type PaginationState,
  type Updater,
} from '@tanstack/vue-table'

const features = tableFeatures({ rowPaginationFeature })
const columns = [{ accessorKey: 'name' }]
const data = ref([{ name: 'Ada' }])
const pagination = ref<PaginationState>({ pageIndex: 0, pageSize: 20 })
const state = computed(() => ({ pagination: pagination.value }))
const table = useTable({
  features,
  columns,
  data,
  state,
  onPaginationChange: (next: Updater<PaginationState>) => {
    pagination.value =
      typeof next === 'function' ? next(pagination.value) : next
  },
})
const pageSize = computed(() => table.atoms.pagination.get().pageSize)

Assign the resolved updater result to the ref. For shared atom ownership, use a stable @tanstack/vue-store atom in atoms.<slice> instead of mirroring the same slice in controlled refs.

For computed-state synchronization failures, updater mistakes, or render boundaries, read reactivity details. If this task changes processing features, run intent load @tanstack/table-core#table-features and read the relevant feature references.

API discovery

Inspect node_modules/@tanstack/vue-table/dist/useTable.d.ts and reactivity.d.ts; inspect the matching core feature declarations for the controlled slice.
