How do I add a custom table to a form in another module in Drupal?

Question

I am trying to make a module to add a table to a form in another module. I found I can add the new data in a module_form_alter hook but how to I get it to run through a theme hook? The module I am trying to modify has a theme hook for the page I want to modify. I don't want to change the original form I just want to add a table with new data below it. Thanks

Arrange your data into table headers and cell rows, and return the output with

return theme('table', $header, $rows, array('class' => 'ifyouwantaclassname'));

That will return data themed in a table. $rows are constructed by looping the dataset and adding an array item.

But you also need to change the structure of the form with a theme hook.

Has a pretty good write up on how to do it.
