Thanks Wolfgang!

The reason for the use of the layer is the following: If I use frames of 
the natural table, then I have this:

\def\arde[#1][#2]{%
\bTABLE
\setupTABLE[frame=off]
\setupTABLE[c][1][rightframe=on]
\bTR
\bTD #1 \eTD
\bTD #2 \eTD
\eTR
\eTABLE}
\setuptolerance[tolerant,stretch]
\starttext
\arde[\input knuth][\input knuth]
\arde[\input knuth][\input knuth]
\stoptext

There you can see the problem, you have to zoom into the pdf: Between 
the two tables, there is a tiny tiny (!) space betweeen the vertical 
lines. Its not a big issue, but it is there.
