How to merge cell of header?

I want to merge cell of header. Can it work as image ?

Hello @quoc27690 ,
Short answer: no. Multiline headers is not supported, nor is merging.
I'd assume you could add a class to your headers using headerClassName on the column and tweak the CSS to make it span multiple columns, but that would mess with all the click behaviors.

Is there any chance of adding support for both multiline headers and merging? It is important for my use case.

Not planned. This adds a lot of complexity that is not balanced with enough added value so far.
