I am a teacher. I have been printing flash cards for my students using
Quark Xpress, but I am hoping to start using Adobe InDesign. I'm not
sure how to make InDesign do what I want, or even if it's possible.

Currently, my Xpress file has a table 3 columns across and 8 rows
down. To make the front and back of each card match up, the tables
have to flow backwards on the back side of the page, like this:

 FRONT:        BACK:
1   2   3       3   2   1
4   5   6       6   5   4
7   8   9       9   8   7
. . .              . . . 

and so on. 

How does one make the text in Adobe InDesign flow right to left in a
table? Can it be done?

This is kind of a tricky question to explain in writing, so please
feel free to ask for clarification. Comments also welcome.
