subcategories in a row vs. one subcategory per row in index display?

[robinna]

Hi all,
I am mostly using subcategories to organize my images and keep my coppermine gallery from being very long and scrolly. My question is this: On my main gallery page, one subcategory displays in each row. Is there a way to make the subcategories themselves fit next to each other horizontally in a table row?

currently you see:
category
subcategory
subcategory
subcategory
etc.

What I want to display is
category
subcategory           subcategory           subcategory            subcategory
etc.

If you look at my site my question might make more sense:

As usual, sorry if I've missed this elsewhere and please just point me in the right direction.
thanks,
robin
