Examples

<script>
  import { createTable, Render } from '@humanspeak/svelte-headless-table';

  const data = [
    { name: 'Ada Lovelace', age: 21 },
    { name: 'Barbara Liskov', age: 52 },
    { name: 'Richard Hamming', age: 38 },
  ];

  const table = createTable(data);

  const columns = table.createColumns([
    table.column({
      header: 'Name',
      accessor: 'name',
    }),
    table.column({
      header: 'Age',
      accessor: 'age',
    }),
  ]);

  const vm = table.createViewModel(columns);
</script>

<table {...vm.current.tableAttrs}>
  <thead>
    {#each vm.current.headerRows as headerRow (headerRow.id)}
      <tr {...headerRow.current.attrs}>
        {#each headerRow.cells as cell (cell.id)}
          <th {...cell.current.attrs}>
            <Render of={cell.render()} />
          </th>
        {/each}
      </tr>
    {/each}
  </thead>
  <tbody {...vm.current.tableBodyAttrs}>
    {#each vm.current.pageRows as row (row.id)}
      <tr {...row.current.attrs}>
        {#each row.cells as cell (cell.id)}
          <td {...cell.current.attrs}>
            <Render of={cell.render()} />
          </td>
        {/each}
      </tr>
    {/each}
  </tbody>
</table>

Every row, cell and the view model itself expose a current object whose values are plain and reactive: read them in the template and they update as plugins change state, with no stores, $ syntax or wrapper components. For data that changes, keep it in $state and pass a getter: createTable(() => items).

Coming from 6.x, where tables were built on Svelte stores? See Migrating to v7.

Custom cells with snippets

Use createSnippetRender to render a cell (or header) with a snippet declared in the same component. Top-level snippets are hoisted, so they can be referenced from <script>.

<script>
  import { createSnippetRender } from '@humanspeak/svelte-headless-table';

  const columns = table.createColumns([
    table.column({
      accessor: 'name',
      header: 'Name',
      cell: ({ value }) => createSnippetRender(nameCell, value),
    }),
  ]);
</script>

{#snippet nameCell(name)}
  <strong>{name}</strong>
{/snippet}
