You can ungroup the tables and then animate the textbox.
But before you do so, you might want to duplicate the table so that if it is
easier to make changes in the future. Then, drag the duplicated table out of
the slide/working area.
To ungroup, right click on the tables, click ungroup.
Then, add the effect on the textbox.
