B4J Question GridPane rowspan and colspan

[stefanogoria]

Anyone knows how I can have functions like Rowspan and/or Colspan using a GridPane ?
Thanks in advance for replay

The simplest way to do it is with the scene builder.

Thanks Erel, sorry for delay.
I think there is also a way using javaObject and RunMethod but I never use it.
Your solution for me it's enough, but just for knowledge, could you please explain other ways ?
Thanks a lot for your kind support.
