Pages supports bidirectional text, so you can enter and edit text written from left to right (such as in English or Chinese) and from right to left (such as in Arabic or Hebrew) in the same document. You can also use bidirectional text in table cells, and you can reverse the direction of tables to accommodate different languages.
The direction of text in table cells is based on the direction of the top-left cell in a left-to-right table, or the top-right cell in a right-to-left table. If one of those cells is empty, the direction is based on the current keyboard (set in the Input menu).
You can change the direction of text in selected cells.
Select the cells.
Click the Text tab at the top of the sidebar on the right, then click the Style button.
If you don’t see a sidebar, or it doesn’t have a Text tab, click 
in the toolbar.
In the Alignment section, click 
.
You can change the table direction so that header rows, column order, and other table elements are reversed.
Click anywhere in the table to select it, then do one of the following:
Choose Format > TableNoBreak > Reverse Table Direction (in the Format menu at the top of your screen).
Click the Table tab at the top of sidebar on the right, then click a Table Direction button at the bottom of the sidebar.
If you don’t see a sidebar, or it doesn’t have a Table tab, click in the toolbar.
When you reverse table order, cell alignment is affected as follows:
Text cells set to auto-align (the default setting) change their text alignment.
Number cells set to auto-align (the default setting) don’t change their number alignment. (Numbers always auto-align to be right-aligned.)
If a cell’s alignment is right, left, or center aligned, it retains that alignment.
If a cell’s alignment is justified, the gap for a partial line changes from being on the right to being on the left.
