Fixed column width overlapping table

HiCntry

I'm using dataTables on two different web pages but it's behaving differently on each. One page works fine and as expected, here: http://www.huts.org/cohutsyurts/amenities.php . The other page had the fixed column on the left overlapping and not lining up correctly with the thead and other td's in the row, here: http://www.huts.org/Reservations/Hut_Amenities.php . The second page does have an additional stylesheet but I haven't found any conflicting styles being applied by it yet. I don't expect anyone to debug this obviously, I was just wondering if this is a common problem or one that has a known fix or anything.
