horizontal scroll bar

I'm currently pulling my hair out trying to - with what I thought would be a simple fix - get a horizontal scroll bar to appear within a View's table.

I have a silly example just to see if anyone can help using Firebug or similar, as the production site is not yet available (I could then apply this fix to the real site).

The Views Table appears at http://www.yousayuk.com/page/about-us under the title 'test-3' and just pulls in some random data to demonstrate how the table stretches beyond that which is expected.
