Override per-column sorting and filtering in TanStack Table by replacing `sortFn` and `filterFn` in column definitions with custom logic or registered built-ins from the `sortFns` and `filterFns` registries.

Custom aggregation for grouped rows in TanStack Table is handled by defining an `aggregationFn` to compute the grouped value, keeping this computation separate from the `aggregatedCell` rendering logic used to display it.

Yes, you can chain filtering into sorting in TanStack Table v9 by attaching custom metadata via `addMeta` during filtering, then accessing `row.columnFiltersMeta` within your custom sort function to rank results by filter relevance.

Implement fuzzy search ranking by overriding the `filterFn` to calculate and store match ranks in column filter meta, then use a custom `sortFn` to read those ranks for deterministic sorting handoff in your React data grid.

Control sort direction for undefined values or descending-first ordering in TanStack Table by configuring the `sortUndefined` and `sortDescFirst` properties within your column definitions for fine-grained sorting behavior.

Yes, TanStack Table supports overriding global filtering for the entire table by setting the table-level `globalFilterFn` property to a custom function or registered named function to change how all rows are filtered.
