[NTG-context] Natural Tables: spaceinbetween not working?

Hi, spaceinbetween seems to have no effect in this example: ======= \setupTABLE [spaceinbetween=25pt,split=yes] \starttext \bTABLE \dorecurse{50}{\bTR \bTD table cell \eTD \bTD table cell \eTD \eTR} \eTABLE \stoptext ====== What am I missing? Best, Denis
