If you mean something like this -
It isn't supported yet in WebLaF and not available in standard Swing either.
There are some examples out there, like this one: http://www.java2s.com/Code/Java/Swing-Components/GroupableGroupHeaderExample.htm But I'm not sure whether it will work or how well it will work.
I've added a separate feature for future addition: #680
But it's most probably not coming anytime soon, so if you need an immediate solution - your best shot is trying to implement one yourself and then replace it later with WebLaF one, once it becomes available.
Will be closing this issue All groupable table header -related discussions will be held in #680
