customizing-feature-behavior

What problem does it solve?

This Skill prevents you from being locked into TanStack Table’s default behaviors by letting you override how rows are filtered, sorted, and grouped per column or globally.

Core Features & Use Cases

• Per-column function overrides: Replace sortFn, filterFn, and aggregationFn with custom logic or registered built-ins.
• Table-level global filtering: Override globalFilterFn to change how the entire table is filtered.
• Cross-feature composition: Chain filtering into sorting using addMeta and row.columnFiltersMeta, and separate grouped value computation (aggregationFn) from rendering (aggregatedCell).
• Use Case: Implement fuzzy search that ranks results in a custom filter, then sorts by that rank while also supporting grouped summaries like weighted averages.

Quick Start

Use the customizing-feature-behavior skill to override column filterFn, sortFn, and aggregationFn so your table’s filtering ranks are preserved into sorting and your grouped rows render computed aggregate values.
