Advanced javascript calendar

The example below shows how to use the calendar column type, with a rule where the second calendar column cannot be greater than the first.

NOTE The filter argument creates a validRange option based on the previous column value. The onbeforechange behavior blocks the user to paste or programmatically overwrite the rule.
