Answer 1

Based on @Kerem's answer, here is the solution I came up with:

In order to make the nested datable like own rows of main datatable, I have overriden the CSS class .ui-dt-c. Check in h:head the style tag for details.

    
    





    
        
            
            
        
    

    #{u.name}
    
        
            #{f.name}
