Well you are using a template that someone else coded - is why.
You need to code it yourself... and make tables with the width being a percentage rather than a certain number of pixels.
Though Im not sure why you would get mad at a forum when the issue clear that you simply dont know how to code...
No one here will be able to just teach you.
Go to the W3schools site and take some tutorials.... That is my suggestion.
Luck.
