great, thanks for the improvement! this solves things brilliantly.
what would be great is the possibility of doing the same thing for more
than a column in the same execution. it is cumbersome to do it over and
over for a large table.
one further improvement would be to automatically add in the layer
property style the summary table as Value map.
should I open feature reqs for this?
All the best, and thanks again.
