[NTG-context] \noalign?

Salvete, which tables allow using \noalign and in what places? E.g., the first of these works, but I'd also like to be allowed the second one (ignore what \pause does for the moment ...): \starttable[|c|c|c|] \HL \NC one \NC two \NC three \NC\AR \HL\noalign{\pause}% \NC one \NC two \NC three \NC\AR \noalign{\pause}\HL \stoptable I assume this has to do with trial typesetting or something like this, but what should I type instead? regards, Christopher
