solid/migrate-v8-to-v9

Migrate TanStack Solid Table from v8 to v9 by renaming createSolidTable to createTable, moving get*RowModel options into _rowModels using create*RowModel factories, and registering _features via tableFeatures(). You must also update state ownership to use per-slice on*Change handlers or atoms.

TanStack Table v9 breaking changes include renaming createSolidTable to createTable, requiring _features via tableFeatures(), moving row models into _rowModels, renaming sortingFn to sortFn, and removing whole-state onStateChange in favor of per-slice handlers or atoms.

Solid Table row models broke in v9 because get*RowModel options were moved into the _rowModels object. You must now supply create*RowModel factories inside _rowModels instead of passing them as top-level options to the table initialization function.

Handle Solid Table v9 state ownership by replacing the removed whole-state onStateChange with per-slice on*Change handlers or atom-based reactive state. This update requires adopting Solid-idiomatic table.state() accessor semantics to preserve sorting and filtering behavior.

Yes, you must fix createColumnHelper generics when migrating to TanStack Table v9. The typing contracts changed during the initialization refactor, requiring updates to ensure your datagrid columns compile and behave correctly.

You can preserve sorting and filtering behavior during a Solid Table v9 migration by adopting the sortFn and filterFn renames alongside per-slice on*Change handlers. This ensures your datagrid state initialization and reactive patterns remain functional.
