Most of the TableControl logic is already implemented
in its implementation class, TableControl_Impl and
most TableControl methods just forward to the
corresponding TableControl_Impl ones.
Implement that approach for more methods by moving the
logic to TableControl_Impl, to make the handling more
consistent and prepare for merging TableControl and
TableControl_Impl in an upcoming commit.
