[NTG-context] \=d in a table: weird behaviour

Hello, It seems that \= and table interact in a strange way in the following example: \starttable[|c|] \NC \=d \NC\NR \stoptable \=d alone works OK. I suggested to use $\rm\overline{d}$ to the one who asked me about it, so it's not really crutial to fix that, I just find it a bit strange. Thanks, Mojca
