Vue Table setup and integration

Before starting, run intent load @tanstack/table-core#core for the shared headless model and stable-input rules.

Setup

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

type Person = { name: string; age: number }
const features = tableFeatures({})
const columns = [
  { accessorKey: 'name', header: 'Name' },
  { accessorKey: 'age', header: 'Age' },
]
const data = ref<Person[]>([{ name: 'Ada', age: 36 }])
const table = useTable({ features, columns, data })
</script>

<template>
  <table>
    <thead>
      <tr v-for="group in table.getHeaderGroups()" :key="group.id">
        <th v-for="header in group.headers" :key="header.id">
          <FlexRender v-if="!header.isPlaceholder" :header="header" />
        </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>

Essential constraints

Use useTable with a ref, computed value, or reactive getter for changing data. Passing data.value captures one array and loses later updates. Keep static features and columns stable; derive transformed arrays with computed.

Table owns models and state. The application owns markup, CSS, interactions, and accessibility. Core-only tables use row.getAllCells(); visibility-aware methods need columnVisibilityFeature. Optional state and APIs require their features. Put row-model slots after their prerequisite features in tableFeatures().
