table row color iteration below headergroup gets messy

Hi,
i am trying agein to improve some pages i already am using with this great library.
At the moment i managed to do some sort of grouping, using a table, similar as in http://www.tinybutstrong.com/apps/examples/tbs_us_examples_grouping.php

ok, works fine.
However in the detail rows i had been using alternate colors,

this keeps working, but gets messy after some headers have passed.
Is there a way to "reset" the rowcount below a each header row, so coloring of the detail rows always start with the same color ??

thanks,

Klemens

Hello, there is no native feature to do this directly.
However, you can us parameter "ondat" to define a customized calculated data field. Then you can use this data field for conditional sections in your template.
