Numbers supports bidirectional text in cells, so within the same spreadsheet, you can have some cells with text written from left to right (such as in English or Chinese) and others with text written from right to left (such as in Arabic or Hebrew).
Note: To change the direction of cell text, your computer must be set up for input sources that use different text directions—for example, one keyboard for typing a right-to-left language, such as Hebrew, and another for typing a left-to-right language, such as English. You can’t reverse the direction of a table. See Set up a keyboard or other input source for another language.
The default direction of text in cells is based on the current keyboard (selected 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.
If you don’t see a sidebar, or the sidebar doesn’t have a Text tab, click 
in the toolbar.
Click the Style button near the top of the sidebar, then in the Alignment section, click 
.
When you change the direction of cell text, the 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.
