Calendar Date Validations

In the example below, filterOptions is used to overwrite the column configuration validRange just before the edit. The rule is that the last column cannot have a date after the previous column date. Additionally, the onbeforechange event behavior blocks the user from pasting or programmatically breaking this rule.
