RadzenDataGridColumn

I wonder if I can merge the column with the same info. For example, the row of ID 1 to 6, I would like to show one Envision in the column of Life Cycle Stage, as shown in the uploaded image.

Demo with possible approach can be found here/

Thanks, I am able to merge the cell. It works. However, when clicking the next page, the column was shifted. Please see the below figure. Please advise what I should do. Thanks!

Checking if there was any solution to the issue or was there any work around implemented for the same.
