Adding Extra Rows and Columns in Category's Page

[MDEE]

Hello

Im trying to find out if i can add more columns and rows in the categories page like the index page that shows different merchandise in the first page

example would be something like im selling shirts and have the category shirts
in there i have like 20 different shirts but it shows on column with ten then next page

i would like to be able to put 20 shirts on the page with 5 rows and four columns
in that one category

is it possible? and does any know how i can set it up like that

thanks
