Is there a way to make multi-line header to table?

For example, we have column A,B,C grouped as X, and column D,E,F grouped as Y.
So, we have actually a two-lines header, there are X and Y at line 1, and A,B,C,D,E,F in line 2.
Of course if we collapse X, ABC will be collapsed either. This would be better.
How to get that?

Hi!

Table component doesn’t support the multiline header. But Vaadin Grid component does. You can see a live example of multiline header here and Vaadin documentation here.

In our documentation you can read how to use Vaadin components in CUBA screens.

We have plans to add the Grid component to CUBA Platform. You can see a status of the task in our issue tracker.
