Cell spanning in version 2.2

[Neil Galarneau]

Is Cell spanning in TableView in Java 7 possible to implement?

I have read Jonathan's FX experience article on the topic. I've seen
in RT-24747 that the code was added into Java 8 last year & then
removed early this year. I didn't see (on this list or in Jira) why it
was removed.

It is ok with me if there the implementation isn't perfect. For
example, if keyboard navigation is a little strange that is ok by me.

Thanks in advance for any advice,

Neil
