IMHO, this is wrong approach. 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.
