so, in order to compare, use 1\\2\\3 here too

\setupTABLE[frame=on] % only for debugging reasons
\setupTABLE[c][1,2][align=lohi] % to center vertically (any better way?)
\bTABLE
\bTR\bTD
    a midaligned parbox:
\eTD\bTD[offset=overlay,width=1em] % 1em wide paragraph
    1 2 3
\eTD\eTR
\bTR\bTD
    a midaligned parbox:
\eTD\bTD[offset=overlay,width=1em] % 1em wide paragraph
    \ruledhbox{1 2} 3
\eTD\eTR
\bTR\bTD
    a midaligned parbox:
\eTD\bTD[offset=overlay,width=1em] % 1em wide paragraph
    1\\2\\3
\eTD\eTR
\eTABLE

tex's ways of determining the optimal paragraph are magic ...
