Hi Geert,

your sample lacks the CSV file. Of course, we don’t need your actual
data, but something to test your sample is required.

BTW, how about using \startembeddedxtable...\stopembeddedxtable instead
of \startxtable...\stopxtable? This has worked for me in some documents.

I don’t understand what you aiming at, but \numrows gives exactly that
information.

If \numrows doesn’t fit your needs, please provide a CSV file with fake
data. I cannot guess why a second loop might be required.

I hope it helps,

Pablo
