How to Align the Buttons at Bottom

Is there a way to align the buttons at the bottom of the table. I see that the plugin attempts to add td tags when one column has more features than another. But the empty tags are obviously the default td height and don’t adjust based on the td in the other columns.

Here’s a pic to show what I mean: http://moderntheorie.com/wp-content/uploads/2013/12/Button-Issue.jpg

Is there a way around this so that the buttons can line up at the bottom. I’m sure there is something stupid easy that I’m completely missing. ;/
