The Grid control has a code snippet for column spanning, and I can see
that the header can have spanned rows. Can I have spanned rows for a
column in the main body? Can that block span rows and columns? Does it
even allow for L shaped merges? Just trying to find out how far away the
merging capabilities are from KTable or what you would expect in a
spreadsheet like Excel or Calc.

Correct. Grid is like most typical widgets. One widget, just drawing
content.

Just thought I'd check in to see if there was any news on this feature
and whether anyone had time to do it?

Yes sorry I meant it would detect and disallow L shapes, i.e.
overlapping regions.

Hi Mark,
Currently the Grid only does column spanning (i.e. horizontal) but not
row spanning (i.e. vertical). That is a feature I'd like to add but I
don't have a timeframe for it.
Regards,
-Chris
p.s. I don't believe Excel even allows L shaped cells. AFAIK it only
allows rectangular merges.

I won't to do a port of Drools Decision Tables, so we'll need this to
proceed:
http://labs.jboss.com/file-access/default/members/drools/ima ges/decisiontable1.png
I'll have a look over the src code see how difficult this is to add.
Does this in reality involve floating areas anchored to a point,
emulating a spreadhseet view with composites? How performant is that,
compared to the KTable approach?

If you have found out something could you file a bugzilla and post the
id so people interest can attach?

So Grid is not working like CompositeTable it is actually drawn more
like KTable? KTable had full L shaped merging, hmm wonder if anything
can be leveraged.
