There are also modules to take care of this kind of thing. Take a look at this node where I give sample code for creating a form and table. Generating your code programattically guarantees that you don't miss any closing tags, and that your HTML is structured properly. It's worth a look, and it makes stuff much easier to maintain, and easier to see the page logic.
