1)Click in the table.
2)Choose Table > Format > Table Designer and go to the Direction tab.
3)Choose the direction in the Direction drop-down list.
4)To change the direction of the text in the selected table, click Apply.
Alternatively, to change the direction of the text in all the tables of the current table format, choose Update All.
