Tanstack Table

This one teaches you the meta field pattern for TanStack Table instead of the closure approach that causes unnecessary re-renders. You hoist your column definitions outside the component, extend the TableMeta interface for type safety, and pass callbacks like onEdit or onDelete through the meta option. The skill includes examples of both the wrong way (columns defined in useMemo that invalidate on every callback change) and the right way (stable columns with dynamic meta). It's opinionated about this specific pattern, which is good because the library gives you enough rope to hang yourself with performance issues if you're not careful about how you wire up interactive cells.
