Tanstack Svelte Table Best Practices

TanStack Svelte Table Best Practices

Treat a table as a static schema paired with reactive instance data and feature-local behavior; this keeps rendering, callbacks, and data updates predictable.

1. Treat columns as static schema and table behavior as instance-local capability.
   • Keep the table contract static and its capabilities feature-local. Pass per-instance callbacks through table meta, and reserve declaration merging for an intentional application-wide contract.
2. Provide changing rows reactively and render definitions through their table-owned context.
   • Preserve reactive ownership with getter-backed options, narrow atom reads, and matching change callbacks.
   • Render definitions, components, and snippets through adapter primitives, since raw definitions lack their table-owned context.
3. Register only the features and implementation functions that the table uses.
   • Compose explicit, tree-shakeable capabilities, including individual filter, sort, and aggregation functions instead of whole registries.
4. Keep reactive ownership and table-object calls explicit.
   • Preserve instance ownership by calling methods through their receiver; rows, cells, columns, and headers use prototype-bound methods.
5. Keep table controls consistent as pages load.
   • Handle selection, sort removal, filters, and pinning without treating loaded rows as the full dataset.
