In excel, when you create a group of rows, it defaults to having the summary inforamtion at the bottom of the group. Your method WorkSheet.Cells.GroupRows performs in this same manner.
However, in excel, you can change the settings for that group to say that the summary information is at the top of that group. Excel menu path is: Data/Group and Outline/Settings....
I have not found how to duplicate this using Aspose. Can you tell me how to accomplish this. If it does not exist, can you add this feature?
Thank you, James
