If the problem is with fitting the table onto A4 paper, you could adjust \tabcolsep, as Ross mentioned, you could also try \resizebox and/or \rotatebox.
\resizebox{\textwidth}{!}{Your table here}
or
\rotatebox{-90}{Your table here}
or
\resizebox{\textwidth}{!}{\rotatebox{-45}{Your table here}}
Hope this helps,
