Here is one attempt, which works correctly. Of course the best solution 
is to forget about the \omit and set the halign preamble correctly. But 
I have not been able to figure that out yet.

\starttext

\def\CMID{\normalTABLEshortrule}

\unprotect
\def\TableNC
  {\checkTABLEautorow
   \nextTABLEgrayline
   \ifnum\currentTABLEcolumn>\maxTABLEcolumn
     \setTABLEerror\TABLEmissingrow
     \handleTABLEerror
   \else
     \global\advance\currentTABLEcolumn \plusone
     \ifnum\currentTABLEcolumn=1\relax
       \normalTABLEquote
     \else
       \fancyTABLEquote
      \fi
   \fi}

\def\fancyTABLEquote      {\unskip\!ttRightGlue&\omit\hskip2em&} % "
\protect

\setuptables[rulethickness=0.03em]

\starttable[s0|l|l|]
  \HL[3]
  \NC Monat     \NC 1965  \NC 1966  \AR
  \NC \CMID     \NC \CMID \NC \CMID \DR
  \NC September \NC 2000  \NC 1700 \AR
  \HL[3]
\stoptable

\stoptext
