You might want to read the information here. With a little effort you should be able to figure it out. With CGI.pm you can do things like this ...

print table({-border=>undef},
           caption('When Should You Eat Your Vegetables?'),
           Tr({-align=>CENTER,-valign=>TOP},
           [
              th(['Vegetable', 'Breakfast','Lunch','Dinner']),
              td(['Tomatoes' , 'no', 'yes', 'yes']),
              td(['Broccoli' , 'no', 'no',  'yes']),
              td(['Onions'   , 'yes','yes', 'yes'])
           ]
           )
        );
