when I post code or quote someone on my board (7.2.2)

code table or wrap what ever you call it is small
only takes up about 50% of the post body if not less
& the hight is alway to short also .
How can I change this ?
is it a css thing or do I have to edit a file ?

Code
this is the code table or wrap I'm talking about
