Table cell borders

I've been trying to style a particular table and can't get it to work properly.

basicaly I just want this one table to have borders round the table and between each cell (like a grid). I've given it's own id and class "table-fees" and I've got the border round the outside but can't get the cell borders to work - can any help please?

It's at http://79.170.40.48/professionalcomm...sh-in-england/ - click on the sub link near the top for Fees to see the table.
