htlatex - need help converting latex to html

Question

I am trying to convert a set of tex file to html. The attached code generates perfect pdf. While it gives the following error with htlatex.

I have not much knowledge of tex so please help by being more verbose as possible.

error:

l.259 --- TeX4ht warning --- \halign translated into linear text --- 
! Missing number, treated as zero. 
<to be read again>
                     \ar:cnt

Well, there are some errors caused by the lack of support for memoir in tex4ht. We fixed that in another question. Now you need to add support for your macros. To do that, you should separate them in package, for example ramneek.sty

Now you need to add configuration for tex4ht, so create file ramneek.4ht. This file is loaded automatically when you use package ramneek.

\NewConfigure{TableBase}{2}
\ConfigureEnv{TableBase}{%
\a:TableBase
}{\b:TableBase}{
\renewcommand\topline{}
\renewcommand\bottomline{}
}{}

\Configure{TableBase}{\HCode{<div class="TableBase">\Hnewline}}{\HCode{</div>\Hnewline}}

\Css{
.TableBase .tabular td{
  border-top:1px solid black;
  border-bottom:1px solid black;
}
}

This code patches environment TableBase, it redefines macros \topline and \bottomline which caused problems and it insert configurable hooks. With \Configure{TableBase} we configure this hook to insert <div class=TableBase> and with \Css command you can configure appereance of the table using cascading stylesheets however you want.
