Many thanks Bastien  for your quick reply.  The best for me  would be to
use the  LaTeX syntax with  tabular, multicol ,  ect. and to  succeed in
html export too. But 
with in the headers the following line: 

#+STYLE: <SCRIPT SRC="/usr/share/jsmath/easy/load.js"></SCRIPT>

and in the .tex file the following code:

\begin{center}
 \begin{tabular}[tb]{cc}
\multicolumn{2}{c}{$ ((p \to q) \to p) \to p $} \\
$ ((\bot \to q) \to \bot) \to \bot $ & $ ((\top \to q) \to \top) \to \top $ \\
$ (\top \to \bot) \to \bot $ & $ \top $ \\
$ \neg \neg \top $ & \\
$ \top $ &   \\
\end{tabular}
\end{center}

I get in iceweasel (i.e. the Firefox of Debian): 


Unknown environment "center" 
Unknown environment "tabular"

... 

I have also tried to use imagemagick, it does not work correctly... 

Again, thanks for your kind help.
