If you have worked on school portals or jobs that requires you to generate a lot of forms on-the-fly, you will understand the need to have some kind of form generator. Especially one that allows you to define the columns and the rows in a grid-like pattern.

Features:
1. It allows you to define the columns and the rows
2. It autoassigns ID for them in an easily themeable manner. i.e if i were to display a 100/1000 grid,
I can predict the IDs of the various textboxes.
3. It allows moving from one editable field to another by using your arrow keys.

Other features in this demo:
1. You can control the number of digits allowed by some fields e.g. 2 digits were used here
2. Crossbrowser compatibility
3. Supports Jquery validation
4. Integrates with drupal cck / views
