hook_theme

There lots of solution available in Drupal to create tabular data with form but the best solution is to use "theme() function" for this. When I was a beginner in Drupal I have created a table using "form API" in which I have included "for loop" and "field type" etc. to achieve this task. That time I don't care of coding standard but my main aim was to finish the task by hook or by crook.
