Tables

Returns every nested table editor for this row, creating (materializing) any that do not exist yet. This builds an editor per child schema — on a deeply-nested collection that cascades into the whole subtree, so prefer materialized for read-only traversals.

Finds the nested table editor for key, creating (materializing) it if it does not exist yet. Returns null only when this row has no child container for that schema.

Already-materialized nested table editors for this row — does NOT create any.
