You can sync Preact TanStack Table state with external atoms by providing your own atoms through `options.atoms`, making them the source of truth that keeps table feature updates in sync. Use `useSelector` and `Subscribe` for reactive reads.

Three reactive surfaces are available: `table.atoms.<slice>` for per-slice readonly reads, `table.store` for flat projections of full table state, and `table.baseAtoms.<slice>` for internal writable state when the table owns the slice.

To persist TanStack Table state to external storage in Preact, use `atom.subscribe(...)` on your externally owned atoms to sync state changes with storage or other external systems imperatively.

Yes, you can share TanStack Table state across multiple Preact components by reusing the same atom identity across components, which ensures consistent state synchronization and cross-component reactivity.

To write updates to externally owned table state slices in Preact, rely on TanStack Table feature APIs to write to the correct owning atom surface, ensuring the application-owned slice atoms remain the source of truth.

Use external slice ownership for Preact datagrids when you need externally persisted state, cross-component synchronization, or narrowly scoped slice subscriptions that require predictable ownership and fine-grained reactivity.
