The worksheet JMesa example shows what an editable table looks like. Note: the ability to add and remove rows is new in version 2.5. I did not implement the add and remove service methods so those actions are not wired up right now in this example. However you can still see the effect of adding and removing rows in this example...the save will just not have any effect on these rows.

Other examples:
Basic
Limit (with AJAX)
Groovy

${presidents}
