Vue Table State, Subscribe & createTableHook

Dependencies

pnpm add @tanstack/vue-table @tanstack/vue-store

@tanstack/vue-store is a peer for createAtom / useSelector. It is only required when you opt into external atoms — basic tables that use initialState or built-in state work without it.

This skill is v9-specific (9.0.0-alpha.48). The hook is useTable for every framework now; the v8 name useVueTable no longer exists.

Setup

Every Vue table call requires features (built from tableFeatures({...})). Row model factories now live on the features object alongside the feature itself. Core row model is automatic; only register paginatedRowModel, sortedRowModel, etc. when you use the matching feature.

<script setup lang="ts">
import { ref } from 'vue'
import {
  FlexRender,
  createColumnHelper,
  createSortedRowModel,
  rowSortingFeature,
  sortFns,
  tableFeatures,
  useTable,
} from '@tanstack/vue-table'

type Person = { firstName: string; lastName: string; age: number }

// Stable identity — declare outside the component or at module scope.
const features = tableFeatures({
  rowSortingFeature,
  sortedRowModel: createSortedRowModel(),
  sortFns,
})
const columnHelper = createColumnHelper<typeof features, Person>()
const columns = columnHelper.columns([
  columnHelper.accessor('firstName', { header: 'First' }),
  columnHelper.accessor('lastName', { header: 'Last' }),
  columnHelper.accessor('age', { header: 'Age' }),
])

const data = ref<Person[]>([])

const table = useTable({
  features,
  columns,
  // Reactive data: pass the ref directly OR a getter — the adapter unwraps.
  data,
})
</script>

<template>
  <table>
    <thead>
      <tr v-for="hg in table.getHeaderGroups()" :key="hg.id">
        <th v-for="h in hg.headers" :key="h.id">
          <FlexRender v-if="!h.isPlaceholder" :header="h" />
        </th>
      </tr>
    </thead>
    <tbody>
      <tr v-for="row in table.getRowModel().rows" :key="row.id">
        <td v-for="cell in row.getAllCells()" :key="cell.id">
          <FlexRender :cell="cell" />
        </td>
      </tr>
    </tbody>
  </table>
</template>

Why this works

The Vue adapter calls vueReactivity() and installs it as coreReactivityFeature automatically (see packages/vue-table/src/useTable.ts):

Readonly atoms back onto computed() refs.
Writable atoms back onto shallowRef().
Subscriptions use watch(source, cb, { flush: 'sync' }), so table updates are visible to Vue render and computed work immediately.

useTable also runs a watch(() => getReactiveOptionDeps(...)) on every option, so passing a ref or computed for data, columns, rowCount, etc. is supported — the table calls setOptions whenever any reactive option changes.

Vue note. table.Subscribe exists for parity with React, but you usually do not need it. Vue's reactivity re-evaluates template reads automatically — wrap reads in computed(...) if you need them outside a template. Do not import React-Compiler workarounds.

Core Patterns

1. The three read surfaces

// (a) Per-slice atom — narrowest, no full state snapshot built
const sorting = table.atoms.sorting.get()

// (b) Flat readonly store — every registered slice as one object
const snapshot = table.state

// (c) Vue selected state — the value returned from useTable's 2nd arg
const table = useTable(
  {
    features,
    columns,
    data,
  },
  (state) => ({ sorting: state.sorting }),
)
table.state.sorting // typed, reactive

table.atoms.<slice> only contains slices for features registered in features. If rowSortingFeature is not registered, table.atoms.sorting is undefined (and TypeScript flags it). This is the v9-specific "missing API" gotcha — register the feature first.

Source: docs/framework/vue/guide/table-state.md (Feature-based State, Accessing Table State).

2. Reactive data with a getter or computed

The adapter accepts a ref/computed for any option. The idiomatic shapes are:

// (a) Pass the ref directly — adapter unwraps via `unref()`
const data = ref(makeData(100))
const table = useTable({ features, columns, data })

// (b) Use a getter when `data` is owned by a parent object
const table = useTable({
  features,
  columns,
  get data() {
    return data.value
  },
})

// (c) Computed when filtering/derivation lives on the client
const filtered = computed(() => data.value.filter(/* … */))
const table = useTable({
  features,
  columns,
  get data() {
    return filtered.value
  },
})

When data.value changes, useTable calls setOptions synchronously and the table re-derives. Source: examples/vue/basic-use-table/src/App.tsx, examples/vue/virtualized-rows/src/App.vue.

3. External atoms (recommended for shared state)

Use createAtom from @tanstack/vue-store; pass through options.atoms. Atoms take precedence over options.state — pick one mechanism per slice.

<script setup lang="ts">
import { ref } from 'vue'
import { createAtom, useSelector } from '@tanstack/vue-store'
import {
  createPaginatedRowModel,
  rowPaginationFeature,
  tableFeatures,
  useTable,
  type PaginationState,
} from '@tanstack/vue-table'

const features = tableFeatures({
  rowPaginationFeature,
  paginatedRowModel: createPaginatedRowModel(),
})

const paginationAtom = createAtom<PaginationState>({
  pageIndex: 0,
  pageSize: 10,
})
const pagination = useSelector(paginationAtom) // reactive ref-like

const data = ref([] as Person[])
const table = useTable({
  features,
  columns,
  data,
  atoms: { pagination: paginationAtom },
  // NOTE: no `onPaginationChange` — `table.setPageIndex()` writes through to the atom.
})
</script>

<template>
  <button @click="table.nextPage()" :disabled="!table.getCanNextPage()">
    Next
  </button>
  <span>Page {{ pagination.value.pageIndex + 1 }}</span>
</template>

Source: examples/vue/basic-external-atoms/src/App.tsx.

4. External `state` + `on[State]Change` with getters

Still supported and convenient for migration paths. The critical rule: pass each slice as a getter so Vue can track .value changes. A raw ref captured in the state object is read once and never re-tracked.

const sorting = ref<SortingState>([])
const pagination = ref<PaginationState>({ pageIndex: 0, pageSize: 10 })

const table = useTable({
  features,
  columns,
  data,
  state: {
    get sorting() {
      return sorting.value
    }, // <- getter
    get pagination() {
      return pagination.value
    }, // <- getter
  },
  onSortingChange: (u) => {
    sorting.value = typeof u === 'function' ? u(sorting.value) : u
  },
  onPaginationChange: (u) => {
    pagination.value = typeof u === 'function' ? u(pagination.value) : u
  },
})

Source: examples/vue/basic-external-state/src/App.tsx, docs/framework/vue/guide/table-state.md (External State).

5. `<FlexRender>` and `table.Subscribe`

<FlexRender> accepts a cell, header, or footer prop (preferred). The legacy :render / :props pattern still works.

<FlexRender :cell="cell" />
<FlexRender :header="header" />
<FlexRender :footer="header" />

<!-- Legacy form -->
<FlexRender :render="cell.column.columnDef.cell" :props="cell.getContext()" />

table.Subscribe mostly mirrors React. It is rarely the right tool in Vue — prefer computed(() => table.atoms.<slice>.get()) or the useTable selector. If you do need it (for cross-store source subscription), it accepts a source prop:

// In a render function or JSX file
return () => (
  <table.Subscribe source={someAtom} selector={(v) => v.someField}>
    {(value) => <span>{value}</span>}
  </table.Subscribe>
)

Common Mistakes

Passing a `ref` to `state.pagination` without a getter (CRITICAL)

// ❌ Captures the ref object; later `pagination.value = …` writes are invisible.
const pagination = ref<PaginationState>({ pageIndex: 0, pageSize: 10 })
const table = useTable({
  features,
  columns,
  data,
  state: { pagination },
})

// ✅ Use a getter so Vue tracks `.value`.
const table = useTable({
  features,
  columns,
  data,
  state: {
    get pagination() {
      return pagination.value
    },
  },
  onPaginationChange: (u) => {
    pagination.value = typeof u === 'function' ? u(pagination.value) : u
  },
})

Source: docs/framework/vue/guide/table-state.md (External State).

Reading `table.atoms.<slice>.get()` outside a reactive context (HIGH)

// ❌ One-shot read at component setup — never updates.
const pagination = table.atoms.pagination.get()

// ✅ Wrap in `computed` so Vue tracks the atom.
const pagination = computed(() => table.atoms.pagination.get())
// or
const table = useTable(opts, (s) => ({ pagination: s.pagination }))
// then read `table.state.pagination`

Using the v8 `useVueTable` name (HIGH)

// ❌ Removed in v9.
import { useVueTable } from '@tanstack/vue-table'

// ✅
import { useTable } from '@tanstack/vue-table'

"API missing" because the feature is not in `features` (CRITICAL, v9-specific)

// ❌ `rowSortingFeature` not registered → `table.setSorting` and `table.atoms.sorting` do not exist.
const features = tableFeatures({})
const table = useTable({ features, columns, data })
table.setSorting([{ id: 'age', desc: true }]) // TS error / runtime no-op

// ✅ Register the feature and its matching row model factory inside tableFeatures.
const features = tableFeatures({
  rowSortingFeature,
  sortedRowModel: createSortedRowModel(),
  sortFns,
})
const table = useTable({ features, columns, data })

Reimplementing built-in state transitions (CRITICAL — #1 AI tell)

// ❌ Hand-rolled sort — bypasses the table's invariants and reset APIs.
const sorting = ref<SortingState>([])
const sorted = computed(() => [...data.value].sort(/* … */))

// ✅ Let the table own it. Use `table.setSorting`, `column.toggleSorting`,
//    `header.column.getToggleSortingHandler()`.

The library exposes setSorting, setColumnFilters, toggleSelected, nextPage, etc. for nearly every state transition.

Hallucinating pre-v9 API names

useVueTable, getCoreRowModel() as an option, createColumnHelper<TData>() (single generic), sortingFn instead of sortFn — all v8 shapes that will not compile. See migrate-v8-to-v9 for the full rename list.

Unstable `features` / `columns` / `data` identity

Declare features, columnHelper, and columns outside <script setup> (at module scope) or use computed. Recreating them every render churns the table's option diff watcher and triggers a setOptions on every render — slow, and external atom slices can flicker.
