svelte/compose-with-tanstack-form

To build editable Svelte tables with form validation, you compose TanStack Table with TanStack Form. The form centralizes row and field state, while the table controls layout, enabling validation and editable cells.

Managing editable cell state in Svelte 5 datagrids is best done by centralizing values in TanStack Form. You drive the table data from form state, preventing bugs when sorting, filtering, paginating, or virtualizing rows.

You wire TanStack Form fields into TanStack Table columns using `renderComponent` to render reusable Svelte field components. These components bind to `form.Field` names formatted as `data[<rowIndex>].<fieldName>`.

Yes, you can use TanStack Table virtualization with an editable form in Svelte. The form owns the structured data state, feeding values to the table, which handles virtualization, row selection, filtering, and pagination.

Editable Svelte tables lose validation state when sorting or paginating if state is scattered across cells. Centralizing per-row and per-field validation in TanStack Form ensures consistent behavior during table operations.

Yes, you need to create a reusable form hook using `createFormHook`. This hook connects TanStack Form to TanStack Table, allowing table data to be driven directly from `form.state.values.data`.
