I would consider this example as a special way to generate a matrix when exporting to LaTeX, then CAPTION is useless here. Also, HTML export will give differently looking result. So, generally, question here is what the use-case to have special transformation of a table for LaTeX export, providing that other export backends never will do any special with given table (or will apply different transformation), and to give a CAPTION to a table. > –Rasmus --- WBR, Vladimir Lomov -- Fear is the greatest salesman. -- Robert Klein
