Cell padding in a cross tab

[drgoatboy]

This is probably really simple...
I have made a cross tab and it is just what I needed.
However in each cell of the table there seems to be loads of padding around the text. i.e. the lines around each cell are not very close to the text itself and I cannot reduce the text box anymore without losing part of the text.

Can I change this?
I know if I select a different cross tab template it reduces the padding but it messes up other formatting that I want to keep.

Any ideas?

Thanks!!
