Please consider the following minimal working example, let's call it mintab.tex (based on the example in here)

\documentclass{article}

\makeatletter
\def\toprule{\noalign{\ifnum0=`}\fi \hrule \@height 2.0pt \hrule
\@height 2pt \@width 0pt \futurelet\@tempa\@xhline}

\def\midrule{\noalign{\ifnum0=`}\fi \hrule \@height 2pt \@width 0pt
\hrule \@height 0.7pt \hrule \@height 2pt \@width 0pt
\futurelet\@tempa\@xhline}

\def\botrule{\noalign{\ifnum0=`}\fi \hrule
\@height 2pt \@width 0pt \hrule \@height 2.0pt
\futurelet\@tempa\@xhline}

\def\hline{\noalign{\ifnum0=`}\fi\hrule \@height .5pt \futurelet
  \reserved@a\@xhline}
\def\@xhline{\ifx\reserved@a\hline\vskip\doublerulesep
  \vskip-0.5pt\fi\ifnum0=`{\fi}}

\def\HD#1#2{\vrule height #1pt depth #2pt width 0pt\relax}
\newcommand{\up}{\HD{12}{0}}% for tables
\newcommand{\down}{\HD{6}{6}}%

the interval is ignored.} \vskip-12pt

This one builds fine with pdflatex mintab.tex; however, if I issue htlatex mintab.tex, it fails with:

$ htlatex mintab.tex
...
(/path/to/texlive/2011/texmf-dist/tex/latex/psnfss/ot1pcr.fd) [3]
[4]

                }
l.58 \toprule{} &
                   & \multicolumn{2}{c}{\it QTL genotypes} \down\\
? 

If you uncomment the "typeouts", this is what you get for the PDF case:

HEREEEEEE
\show \noalign {\hrule height2.0pt \hrule height2pt width0pt \futurelet }
> \toprule=macro:
->\noalign {\ifnum 0=`}\fi \hrule \@height 2.0pt \hrule \@height 2pt \@width 0p
t \futurelet \@tempa \@xhline .
l.52 \show\toprule

? 
OUT

and for the htlatex case, it 'crashes' and you have to press a ENTER a couple of times to list through all the errors:

HEREEEEEE
! Argument of \g:Advance has an extra }.
<inserted text> 
                \par

l.52 \show\toprule

? 
OUT

Strangely, you cannot even show this \g:Advance:

? i
insert>\show\g:Advance
> \g=undefined.
<insert>  \show\g
                 :Advance
l.59 \toprule{} &
                   & \multicolumn{2}{c}{\it QTL genotypes} \down\\

I'm pretty sure this has something to do with the \toprule command, but I cannot tell what (maybe the backtick?)

Well, anyone have an idea, how I can modify this file so it also builds with htlatex?

If you load booktabs, remove the (re)definitions of \toprule, \midrule, \botrule, \hline and \@xhline, changing \botrule into \bottomrule, the file compiles. –  egreg Apr 6 '12 at 13:29
    
Many thanks for that @egreg - indeed, it builds, and the table is fine in HTML! Also \def\botrule{\bottomrule} worked for me. The problem is - I originally wanted to run mk4ht oolatex mintab.tex, which failed the same way; now the mk4ht oolatex passes fine - but only table headers are output, no table data rows. Any ideas how to fix that? Thanks again - cheers! –  sdaau Apr 6 '12 at 13:46
    
Sorry, no idea. I never use the .odt format, so I've never been interested in transforming LaTeX to that format. –  egreg Apr 6 '12 at 13:53
    
Cheers @egreg - thanks for the feedback! –  sdaau Apr 6 '12 at 13:54
