Hi, I've been searching for this module for a while now
After a couple of false starts, I now have it doing pretty much what I wanted it for.
BUT... and there's always a BUT.. there's one extra tweak that I'd like.

My requirement was to be able to tabulate a set of features into an 'at a glance' table.
e.g.

                   A   B  C  D
Feature 1          Y   Y  
Feature 2               Y   Y   Y
Feature 3          Y        Y

where the raw data was a set of nodes ( Feature 1 through Feature 3 are the node titles) with a multi-select taxonomy
for the columns (term values A,B,C,D)
The 'Y' is just to indicate that the Term applies to the feature. I got the 'Y' by rewriting the body field for the node...

And marking the other fields (Title and Term) as Exclude.

All well and good so far.

Now I want to be able to create different versions of the 'Feature n' nodes
when there are slight differences depending on the taxonomy terms.
e.g. I want to set a range of values for a particular feature and show this for each term where it's different.
Having created 3 new nodes with the same title, I currently get something like this.

                  A   B  C  D
Feature 4         x
Feature 4               y  y
Feature 4                    z  z

what I'd like is all the results for "Feature 4" to be accumulated into one row.

Feature 4        x   y   yz   z

In my case I won't get the yz situation, except in a data error.

My question is: can you help me to change the logic in the render() function ( tablegroup_plugin_style_tablegroup.inc )
to make it happen.

Thanks in advance for any help.. Herb @ bobbing wide
