Migrating from TanStack Table

TanStack Table (formerly React Table v8) is the closest conceptual sibling to sv-grid - both are "headless data grid" libraries with explicit row-model pipelines. If you already think in createTable() + getCoreRowModel(), this is a half-day port.

Estimated effort: 30 min per grid for read-only views, 2-4 hours for editing-heavy grids.

Vocabulary cheat sheet

TanStack Table	sv-grid
`useReactTable({...})`	`createSvGrid({...})` or `<SvGrid>`
`getCoreRowModel()`	`createCoreRowModel()`
`getSortedRowModel()`	Auto-registered by `rowSortingFeature`
`getFilteredRowModel()`	Auto-registered by `columnFilteringFeature`
`getPaginationRowModel()`	Built in; toggle with `showPagination`
`getGroupedRowModel()`	`columnGroupingFeature` + `api.setGroupBy()`
`getExpandedRowModel()`	`rowExpandingFeature`
`flexRender(col.cell, ctx)`	`renderSnippet(MyCell, props)` OR string field
`columnHelper.accessor('field')`	`{ field: 'field' }` directly
`table.getRowModel().rows`	`api.getDisplayedRows()`
`table.setColumnFilters(...)`	`api.setFilter(id, {...})` per column
`meta` (column / table)	n/a - use column `cellClass` / `cell` instead

Imports

- import {
-   useReactTable, getCoreRowModel, getSortedRowModel, getFilteredRowModel,
-   flexRender, createColumnHelper,
- } from '@tanstack/react-table'

+ import {
+   SvGrid, tableFeatures, rowSortingFeature, columnFilteringFeature,
+   renderSnippet, type ColumnDef,
+ } from 'sv-grid-community'

Column definitions

- const columnHelper = createColumnHelper<Order>()
- const columns = [
-   columnHelper.accessor('orderId',  { header: 'Order ID' }),
-   columnHelper.accessor('amount',   { header: 'Amount', cell: ({ getValue }) => fmt(getValue<number>()) }),
- ]

+ const columns: ColumnDef<typeof features, Order>[] = [
+   { field: 'orderId', header: 'Order ID' },
+   { field: 'amount',  header: 'Amount', format: { type: 'currency', currency: 'USD' } },
+ ]

The accessorFn form is the same:

- columnHelper.accessor((row) => row.profile.name, { id: 'name', header: 'Name' })

+ { id: 'name', accessorFn: (row) => row.profile.name, header: 'Name' }

Mounting

- const table = useReactTable({
-   data, columns,
-   getCoreRowModel:       getCoreRowModel(),
-   getSortedRowModel:     getSortedRowModel(),
-   getFilteredRowModel:   getFilteredRowModel(),
- })
- return (
-   <table>
-     <thead>{table.getHeaderGroups().map(/* ... */)}</thead>
-     <tbody>{table.getRowModel().rows.map(/* ... */)}</tbody>
-   </table>
- )

+ const features = tableFeatures({ rowSortingFeature, columnFilteringFeature })
+
+ <SvGrid data={rows} columns={columns} features={features} />

Sv-grid bundles the render + virtualization. No <table> you have to author yourself.

Imperative state

TanStack Table	sv-grid
`table.setColumnFilters([{id, value}])`	`api.setFilter(id, { operator: 'contains', value })`
`table.getColumn('id')?.setFilterValue(v)`	`api.setFilter(id, { operator: 'contains', value: v })`
`table.setSorting([{id, desc}])`	`api.setSort(id, desc ? 'desc' : 'asc')`
`table.setRowSelection(state)`	n/a - use `api.clearRowSelection()` + UI events
`table.toggleAllRowsExpanded()`	`api.expandAllGroups()`
`table.getColumn('x').toggleVisibility()`	`api.setColumnVisible('x', false)`
`table.options.meta?.foo`	Pass through component props / `$state`

Custom cells

- {
-   header: 'Status',
-   cell: ({ row }) => <Badge tone={row.original.status} />,
- }

+ {
+   field: 'status', header: 'Status',
+   cell: (ctx) => renderSnippet(StatusCell, { tone: ctx.row.original.status }),
+ }

renderSnippet accepts any Svelte 5 snippet; renderComponent accepts a regular component if you prefer SFCs.

Server-side data

- const [pagination, setPagination] = useState({pageIndex: 0, pageSize: 25})
- const [sorting, setSorting]       = useState([])
- const table = useReactTable({
-   data, columns, manualPagination: true, manualSorting: true,
-   state: { pagination, sorting },
-   onPaginationChange: setPagination,
-   onSortingChange:    setSorting,
- })

+ <SvGrid
+   data={rows} columns={columns} features={features}
+   externalSort={true}
+   externalFilter={true}
+   onSortingChange={(clauses) => refetch({ sort: clauses })}
+   onFiltersChange={(f)       => refetch({ filters: f.columns })}
+ />

What you get for free vs TanStack Table

Renderer. TanStack is headless-only; you draw the <table>. Sv-grid ships an opinionated, fast renderer with virtualization, scroll, sticky headers, column resize, keyboard nav, ARIA.
Inline editing. editorType: 'text' | 'number' | 'date' | 'list' | ... - built-in editors with parsing + validation hooks.
CSP-clean. No eval. The shipped tests confirm.
Pro features. Export, import, pivot, AI - in one paid add-on.

What you give up

React-first ecosystem. Sv-grid is Svelte 5-native. There's no React wrapper.
meta for arbitrary side-channel state. Pass props directly.
@tanstack/match-sorter-utils integration. The grid's filter has a contains operator; if you need fuzzy match, plug your matcher in via the column's cell snippet or use externalFilter={true} and run the matcher yourself.

Frequently asked questions

How long does it take to migrate from TanStack Table to SvGrid?

About 30 minutes per read-only grid and 2-4 hours for editing-heavy grids. Both libraries use explicit row-model pipelines, so createTable() + getCoreRowModel() maps almost directly onto createSvGrid() + createCoreRowModel().

Why switch from TanStack Table to SvGrid on Svelte 5?

TanStack Table is headless-only and multi-framework, so you build the entire DOM, virtualization, filter UI, and editing layer yourself. SvGrid keeps the headless core but ships a batteries-included <SvGrid> render component - virtualization, Excel-style filters, cell selection, and inline editing work in one prop pass.

Is SvGrid free like TanStack Table?

Yes - sv-grid-community is MIT-licensed, like TanStack Table. SvGrid additionally offers an optional paid sv-grid-pro pack for export, pivot, and import, which TanStack Table does not provide at all.
