Give your question a meaningful title!

• Use sort; you've not stated if it's a numeric grade or not.
• You want to type perldoc CGI.pm and look for table,Tr & td.

If this is homework please remember:

• use strict and -w. Comment frequently, Lecturers love that.
• Include a comment acknowledging our help, perhaps with a URL to your post.
• You'll be a better Perl Hacker if you look for answers thus:
  1. perldoc (for your Perl distro) & www.perldoc.com
  2. CPAN
  3. A wealth of books ;-)
  4. Perlmonks (Perl FAQ, the Search button (top left) and Super Search, then SOPW).
  (it's a hubris thing ;^)
