Hi Aditya,

what do you think about

\setuptables
  [\c!columndistance=2em]

\def\!tfSetVrule{%
  \!thToksEdef\!taRuleColumnTemplate={%
    \noexpand\hfil
    \noexpand\vrule
    \noexpand\!thWidth
    \ifnum \!tgCode=1
      \ifx \!tgValue\empty
        \the\LineThicknessFactor      % Default integer
      \else
        \!tgValue                     % User-specified integer
      \fi
      \!taLTU                         % \LineThicknessUnit
    \else
      \!tgValue                       % User-specified dimension
    \fi
    ####%
    \noexpand\hfil
    \the\!taRuleColumnTemplate%      % has \tabskips, when column number=0
    \ifnum\!taColumnNumber=\zerocount\else\tabskip\@@ticolumndistance\fi}%ADDED
(should be configurable)
  \!tfAdjoinPriorColumn}

I changed your hard code 2em value for \tabskip to a parameter in \setuptables.

Wolfgang
