Front end grouping by column (common type) in tables

First, they keyword search and multiple layers of filtering are awesome.. as is the ability to group common records in a column of a table..

However, this is only available from the back end.. It would be great if you could add a check box like (inline editing, allow keyword search, allow user pagination, etc) on the back end, that would allow users to determine if they want to group records from the front end.
