DataTable Fixed Column doesn't show scrollable area when using themes

charis58

When using jQuery DataTable FixedColumn with a jQuery UI theme the scrollable X area doesn't appear.

Please see sample here:

However if I remove the theme ("bJQueryUI": false) then it will work as you can see here:

What am I missing here ? Thank you for your help.
