Expanding the Right Margin

I am using the FClub Theme and love the way it looks but there is too much space on the right hand side. This is a particular problem on pages such as “Schedule” where I am trying to display a table. The more columns I add the smaller the other table columns becomes – yet there is still a lot of room on the right filled with white space.

Is there anyway to add some additional CSS or some other method to change the right margin.

Suggestions / Help?
