Change the way taxonomy lists nodes

Hi,

I used taxonomy on my site, but i want to change the way taxonomy lists the nodes.
What i mean is when someone browses to 'taxonomy/term/', the nodes from that term are displayed in a standard node view (title, teaser, etc..)
However, i would like to display them in the form of a table, to save page space and be able to display some more on 1 page.

How would i manage to do this?
So far i wrote my own modules and showed things the way i wanted, but this is a modification close to the core i think, so i don't know how i would do this...
