[NTG-context] line with height=0 in TABLE

Hello, I would like to have a line with zero height in a TABLE, but it seems to be more difficult, than I thought: \starttext \setupTABLE[r][2][height=0pt,offset=0pt] \bTABLE \bTR \bTD bla \eTD \eTR \bTR \bTD \eTD \eTR \bTR \bTD bla \eTD \eTR \eTABLE \stoptext There is still some height in line 2... How could I get rid of this please? Greetings, Peter -- http://pmrb.free.fr/contact/
