TTableScope class
Provides table context to descendants.
TTableScope allows deep descendants in a table (like editable cells)
to access shared state, such as the list controller or expansion mode.
Note: The active editable cell is tracked separately by TTableCellScope to avoid unnecessary subtree rebuilds when a cell enters or exits edit mode.
