Svelte Example: Basic Create Table

GitHub StackBlitz CodeSandbox

<script lang="ts">
  // This example uses the standalone `createTable` function to create a table without the `createTableHook` util.

  import { createTable, FlexRender, tableFeatures
  } from '@tanstack/svelte-table'
  import type { ColumnDef } from '@tanstack/svelte-table'
  import { makeData, type Person } from './makeData'
  import './index.css'

  // 1. New in V9! Tell the table which features and row models we want to use. In this case, this will be a basic table with no additional features
  const features = tableFeatures({
  }) // util method to create sharable TFeatures object/type

  // 4. Define the columns for your table. This uses the new `ColumnDef` type to define columns.
  //    Alternatively, check out the createTableHook/createAppColumnHelper util for an even more type-safe way to define columns.
  const columns: Array<ColumnDef<typeof features, Person>> = [
    {
      accessorKey: 'firstName', // accessorKey method (most common for simple use-cases)
      header: 'First Name',
      cell: (info) => info.getValue(),
    },
    {
      accessorFn: (row) => row.lastName, // accessorFn used (alternative) along with a custom id
      id: 'lastName',
      header: () => 'Last Name',
      cell: (info) => info.getValue(),
    },
    {
      accessorFn: (row) => Number(row.age), // accessorFn used to transform the data
      id: 'age',
      header: () => 'Age',
      cell: (info) => info.renderValue(),
    },
    {
      accessorKey: 'visits',
      header: () => 'Visits',
    },
    {
      accessorKey: 'status',
      header: 'Status',
    },
    {
      accessorKey: 'progress',
      header: 'Profile Progress',
    },
  ]

  // 5. Store data with a $state rune for reactivity
  let data = $state(makeData(20))
  const refreshData = () => { data = makeData(20) }
  const stressTest = () => { data = makeData(1_000) }

  // 6. Create the table instance with required features, columns, and data
  const table = createTable({
    debugTable: true,
    features, // new required option in V9. Tell the table which features you are importing and using (better tree-shaking)
    columns,
    get data() {
      return data
    },
    // add additional table options here
  })
</script>

<!-- 7. Render your table markup from the table instance APIs -->
<div class="demo-root">
  <div>
    <button onclick={() => refreshData()
    }>Regenerate Data</button>
    <button onclick={() => stressTest()}>Stress Test (1k rows)</button>
