The nth-child({odd|even}) CSS Selector should provide the desired functionality, at least for HTML, but the structure will need to modified so that there is some single element that represents a single rowgroup. I tried (not too hard) to key off of the presence of the "rowspan" attribute but that does not seem possible. https://www.w3schools.com/cssref/sel_nth-child.asp David J.
