Limit table width?

Gravity Forms Directory version: 3.6.1.2

I did this:
Set up a directory where Illinois track coaches can list their upcoming meets

I expected the plugin to do this:
List all the columns on a full-width page

Instead it did this:
As coaches have entered information, the table has grown and I don’t know how to limit the width of it. It is now cutting off the last few columns.

Here’s a link to see what I mean: http://itccca.com/2014-summer-meets/

Thanks!
