There is no direct support for {multicol}
within LaTeX2HTML, so the \newcolumntype
command is not understood by it.

There is no real reason to support this, because the
  8cm  width that you specify may be appropriate for
a PDF producing a printed page, but may be quite
inappropriate for an HTML table on a webpage.

There are various ways to make this work.
e.g.
  (a) just use   \begin{tabular}{lp{8cm}}

or
  (b) put the table-header line into a macro, but allow
      the macro to expand differently for PDF and HTML.
viz.
     \usepackage{html}  %  always use this with LaTeX2HTML
     %begin{latexonly}
      \usepackage{multicol}
      \newcolumntype{H}{p{8cm}}
      \newcommand{\mytablestart}{\begin{tabular}{lH}}
     %end{latexonly}
     \begin{htmlonly}
      \newcommand{\mytablestart}{\begin{tabular}{ll}}
     \end{htmlonly}

Then specify your tables as:

    \mytablestart
     	\multicolumn{2}{c}{some headline}\\\hline
	cell 1	&	cell2\\
    \end{tabular}


Alternatively, try something similar using
   \newenvironment ...
instead of \newcommand .
