[NTG-context] applying properties to columns / rows in xtables

Dear list, having this basic xtable (adapted from xtables-mkiv.pdf): \starttext \startxtable[option=stretch] \startxrow \startxcell one \stopxcell \startxcell two \stopxcell \stopxrow \startxrow \startxcell alpha \stopxcell \startxcell beta \stopxcell \stopxrow \stopxtable \stoptext Is there any way to apply properties to the first column and the second column without having to add an identifier to each xcell? In this sample, it would be easy. In a longer xtable, I would like to avoid it :-). Many thanks for your help, Pablo -- http://www.ousia.tk
