Having the ability to group in the table element was a fantastic addition. My only complaint is that when a column is grouped, it is being duplicated. When I made it so the parent column was hidden to not have duplicated columns, it removed it from the grouped column dropdown since you can't group by hidden columns.
If we could either not duplicate columns, or better yet, be able to group by hidden columns, that would be perfect, and allow us to use this feature.
Also, it would be great if we could toggle which columns we want users to be able to group by. Most of the columns in our table don't make sense to group by.
Example with duplicate columns:
Example when I set the column to hidden when it is included in the group by aggregation (allCampaignsTable.groupByColumns)
