I hope this is a simple question - Is there any way to insert a row separator after arbitrary rows? I have a number of rows that belong to different 'groups' and I would like to have some visual indication of 'group' separation.
You can use the RowSpacingBefore or RowSpacingAfter property on the row to insert a space. But you have to be careful about when you do this, since the spacing is associated with the row. If you add a space and then sort, for example, the spacing will stick with the row it was on. So you have to clear out the spacing if the order of the rows changes.
