number of sub categories per line?

[ne0beatsm0rp98]

Hi, I am looking for a way to display my sub categories say 3 per line per category.

For example > http://www.computerwormsliverpool.com/shop/desktoppcs
On this page i want to have them 3 sub categories on the same line, yet on http://www.computerwormsliverpool.com/shop I want to keep them as 2 per line.
I know in settings you can change how many categories per line, but that is sitewide, i just want to change how many per category, so say in Laptops there would be say 4 per line.

Any ideas peepsS?
