Multiheaders with complex structure in table area of Gantt

Gantt
#1

I’m trying to implement multiheaders in the table area of Gantt control, for some headers I need them to span across several columns. Please see a screenshot, I need the Header A to span across 3 columns which is shown with the red border.

Can you please suggest, how I can achieve that.
