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.
