You can do that with the code there, you can grab the columns and make them bigger. You can switch the columns..
As the documentaiotn says
This page represent adjustable table.
The following functionality available:
1. Scrolling of the table body with always visible header.
2. Changing column width by using drag-and-drop. Just press the mouse button on a border and change the width.
3. Column swapping. Press the mouse on a column header, and drag it to a column to swap. You will see result once you release the button.
