Dynamic Header Generation Based on Column Count in MUI DataGrid

[mahammahmood]

The problem in depth

I'm using MUI DataGrid, and I want the header row in the Excel export to be dynamically generated, spanning across all columns. This header should display information such as the download timestamp and user info, with a custom background color. Currently, I need to set a fixed column count, so it doesn’t adjust dynamically based on the actual column count. Is there a solution to achieve this functionality?

Here is the live demo:
