[NTG-context] Distance between table rows

Hi all, Trying to make my life a bit easier to add distances between tabulate rows. Found the \TB macro on the wiki. But why does below code _not_ add extra space when using the freshly defined \SR command below. So between the _second_ and _third_ row? Some TeX expansion thing going on here? ``` \define\SR   {\NC\NR\TB[halfline]} \starttabulate[|r|l|]   \NC one   \NC two   \NC\NR   \NC two   \NC three \SR   \NC four  \NC five  \NC\NR   \TB[halfline]   \NC five  \NC six \NC\NR \stoptabulate ``` Cheers, Tim
