[NTG-context] setting row height?

What is the (preferred) way to set the height of table rows? e.g. the online documentation tells me how to set the width, not the height. or how to set the height of the table? \starttable[*{4}{|w(7mm)}|][textwidth=max]\HL[5] \VL[5]{1} \VL[1]{0} \VL[5]{2} \VL[1]{8} \VL[5]\AR\HL[1] \VL[5]{8} \VL[1]{~} \VL[5]{~} \VL[1]{1} \VL[5]\AR\HL[5] \VL[5]{0} \VL[1]{~} \VL[5]{~} \VL[1]{2} \VL[5]\AR\HL[1] \VL[5]{2} \VL[1]{8} \VL[5]{1} \VL[1]{0} \VL[5]\AR\HL[5] \stoptable Thanks .F
