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. Jo.
