I have tried colspan specifically but it does not work too. The thing  
is, when i colspan the header, it works. But when I do it to both, there  
seems to be no change in the table’s colspan. What is happening? PLEASE  
HELP!

This isn’t really a question for the Radiant list. Try asking the  
question on [http://www.webdesign-l.com/](http://www.webdesign-l.com/)

Aside from that, it’s not clear to me what you are trying to do.  
First, simplify your HTML to the bare essentials.  
Then validate [The W3C Markup Validation Service](http://validator.w3.org/#validate_by_input) You seem to  
have a **element as a child of your first , which is invalid.  
Lastly, I don’t see colspan anywhere in your code.**
