Auto-size column should consider width of aggregate columns

Currently the aggregate columns are not considered when you have auto sized columns. This usually will force a scrollbar which in many cases is undesirable. 
In my use case, I hide the column being grouped by (e.g. grouping by 'date' hides the 'date' column), but even though I have a few auto columns when I group by it goes passed the width I set. Forcing an ugly scroll when there are only a few columns.
I know that you guys aren't really supporting 2.0.X any more but it would be a big boon as I know many other devs have had this issue.
