Table Header Formatting and Grouping

[#1]

Dear Expert/Team,

Is there is any way to get below type of group columns header in table(Straight Table).

Or for better readability you can stick some text boxes in the header with 'top' layer, 100% transparency options checked. Before that you can create extra spaces in header by wrapping the header text....just a workaround only...

Nice Idea, But we share this information in excel or PDF format then its will not show in same format.
