Multi-line row table ?

Hello,

I have a normal table (see first attachment image)

And I would like to be able to have the table like in the second attachment image.

What is the best way to do it ?

Thanks for all.

I would say, it is not possible. What would be possible: Use one single column and add a component in it, displaying the wanted result. The downside of this approach is, that you loose the ability to sort the table.

For this case, sorting is not a problem.

So you think that I have to develop a custom row component ? is it possible ?

Instead, would it be possible to to something near my needs with a custom TreeTable ?

Don’t know what is possible with the TreeTable as I didn’t try it out yet, but a custom “row-component” is pretty easy. See
Book of Vaadin: Table
, especially section 5.14.2 “Components inside a Table” as a starting-point.
