This looks like you are trying to build the visual
effect of a single column of numbers
2.3
3.2
etc,
by in fact using 2 columns juxtaposed, separated
by a constant '.' between those columns.

Sorry, there's no way LaTeX2HTML can work out that
that is what you are trying to do.

HTML is for laying-out information in a clear, regular way
so that it's meaning is retained and easily extracted.
If you really do mean 2.3  instead of having three separate
items of  2 & '.' & 3 , then that is how you should construct
the {tabular}.

The HTML language is not a page-description language, like TeX.
So you can never expect such trickery using @{..} sequences
to give you a satisfactory result.

My best advice for you is to include two separate {tabular}
environments, within "conditional" environments:

\usepackage{html}   %  you should *always* load this for LaTeX2HTML

%begin{latexonly}
\begin{tabular}{|l| r@{.}l| r@{.}l|}
\hline
ahoj & \multicolumn{2}{|c|}{nazdar} & \multicolumn{2}{|c|}{cau} \\
martin &  2&3   & 3&2 \\
\hline
\end{tabular}
%end{latexonly}
%
\begin{htmlonly}
\begin{tabular}{|l|c|c|}
\hline
ahoj & nazdar & cau \\
martin & 2.3  & 3.2 \\
\hline
\end{tabular}
\end{htmlonly}

Now you will get you prettily constructed version in LaTeX,
and a proper logically constructed version in HTML.
