export const features = tableFeatures({ rowSortingFeature, sortedRowModel: createSortedRowModel(), sortFns: { alphanumeric: sortFn_alphanumeric }, })

Pass the stable `features` object to the installed adapter constructor. The concrete registry determines optional APIs, options, state slices, and their types. The core row model is automatic; a custom core model uses `coreRowModel`.

## Registration rules

- Register each prerequisite feature before its dependent slot in the same `tableFeatures` call. A processing factory alone cannot install that feature's APIs or state.
- Row-model factories use `create*RowModel()` feature slots. Their names and prerequisites are in the feature reference. They take no function-registry arguments.
- `filterFns`, `sortFns`, and `aggregationFns` are feature slots, not table options. They require `columnFilteringFeature`, `rowSortingFeature`, and `rowAggregationFeature`, respectively.
- Import individual built-ins such as `sortFn_alphanumeric` and register their conventional keys. Those keys become typed string names; `'auto'` can resolve only registered functions. Pass a function directly when a column needs no named registry entry. Full registry exports bundle every built-in.
- `columnResizingFeature` requires `columnSizingFeature`; `globalFilteringFeature` requires `columnFilteringFeature`. Check installed `FeatureSlotPrereqs` for other dependencies.
- Use explicit features for normal construction. `stockFeatures` is a deliberate all-features convenience or temporary migration aid, with the corresponding bundle cost.

A missing API can mean missing registration. Check the concrete feature object before casting, recreating an API, or assuming v9 removed it.

## Select references by the requested change

Read only references needed for the requested behavior and its dependencies, including features being added. An unrelated feature already registered on the table does not make its reference necessary.

For controlled state or reset behavior, read [shared state](../table-state/SKILL.md) and load the installed adapter's state skill for reactive wiring.

## Installed API discovery

Inspect `node_modules/@tanstack/table-core/dist/types/TableFeatures.d.ts` for slots and `FeatureSlotPrereqs`. Follow `dist/features/<feature>/` for exact state, option, and instance declarations. Each reference names its feature directory.
