Use case

When using the PaginatedDataTable widget, I found that I couldn't directly set the color for the table header. However, upon inspecting the class of PaginatedDataTable, I noticed that it utilizes the DataTable widget internally. The DataTable widget has a parameter called "headingRowColor," which allows you to set the header color.

To achieve the desired header color for PaginatedDataTable, I ended up modifying the PaginatedDataTable class. I added an additional property to this class, and then passed this property through to the underlying DataTable class. As a result, I was able to set the header color for my PaginatedDataTable.

Proposal

This is before i modify the class.

And this is after i modify the class.

So, this is the code after i modify,PaginatedDataTable with paramater headingRowColor.
