Grouping in table

I need to group some information on my table.
I used the jqgrid to this example.

Can i do this using vaadin?

Thank you

I think you can use the TreeTable to do something like this.
I can’t find a chapter about it in the book, but you can find the original code sample

But note that starting from Vaadin 6.7 it is included by default so you don’t need to install the add-on
