[NTG-context] rulethickness in \setupTABLE

Hello, I have 2 rows, and I would like to have a thick rule on the top and the bottom of the table, and in the middle a thin rule. I do this the following way: \starttext \setupTABLE[frame=off] \setupTABLE[r][1][topframe=on,rulethickness=1pt] \setupTABLE[r][2][topframe=on,rulethickness=0.3pt,offset=0pt,height=0pt] \setupTABLE[r][3][bottomframe=on,rulethickness=1pt] \bTABLE \bTR \bTD bla \eTD \eTR \bTR \eTR \bTR \bTD bla \eTD \eTR \eTABLE \stoptext Is there a cleaner way to achieve this?
