[tex4ht] future support for multicols in htlatex?

[Jagath AR]

Hi Nasser,
Please change the following line:

\ConfigureEnv{multicols}{}{}{}{}

in the Jagath.cfg by:

\ConfigureEnv{multicols}
   {\par\IgnorePar\EndP
    \gHAdvance\MultiCols by 1\relax
    %\HCode{<table class="multicols"
    %                 id="multicols-\MultiCols"><tr><td
class="multicol-1">}%
    \let\sv:HCol=\HCol
    \bgroup  \gHAssign\HCol=1\relax
   }
   {\egroup
    \global\let\HCol=\sv:HCol
    \ifvmode\IgnorePar\fi\EndP
    %\HCode{</td></tr></table>}\par
   }
   {}{}

This will fix the problem.

Regards
Jagath
