I know that ng-grid uses aggregation to group rows[1], so it's not officially supported.
Is there a nice workaround to create a header of aggregation without a row? Or way to use an empty row and don't display it?
I need to aggregate users by group, but I have to list all groups without users too.
Something like:
Group 1 (users : 5) -User 1 -User 2 -User 3 -User 4 -User 5 Group 2 (users: 0) Group 3 (users: 1) - User 6
