How to merge datagridview columns?

RD Design

Hi,

I have a datagridview on windows form.Problem is there are some columns I need to merge in to another column.Tried to inllustrate what I want to do in this image.

I have more than 40 columns in right side with some empty columns too.So all should merge with "heading 1" column.Empty cells can be ignored.There are about 15 rows and how can I merge these values with c# code?

What I want actually run time merge cells.Any cell next to "Value 9" should merge with it (As per above image)

you mean to say at runtime you want to decide which columns are to be merged?

if not, then I suggest to fetch result from DB in such a way that the column values are in the format you want to show on UI
