Insert row in middle of table

I have a a Group made up of Rich Text docs, one of which is a table. It’s about a dozen rows, and two columns. I now want to add a new row in the middle of the of the other rows, but I can’t figure out how to do it.

As a workaround, I’ve added a new row at the bottom and copied and pasted the data from each row one row down, thus opening up a newly empty row in the middle, but there must be an easier way. Yes?

This is completely handled by Mac OS X but I couldn’t find an easier way either.
