Datatable with a list of featured

Hi,

I have a problem with adjusting datatables to my project.
In short, I need a double sorting table. For example: At the begin of sorting in need a rows with class "red", then the rest.

Everything outlined in the picture below:

Is it possible at all ?
I tried to create two tables, but I had some problems with filtering both in one time.

I'm looking forward to hearing from you :)

Thanks, Bartek
