Is it possible to load a LaTeX package and/or use its features on this site? In my case, I'd need to load multirow to make block matrixes. Is that possible? Or is there a way to make a block matrix without multirow on this site? If so, which is it?
• It is, perhaps, bad form, but you could do the table in $\LaTeX$ and the load it here as an image. This is what you have to do it you want to draw a picture. – user1729 Apr 25 '14 at 12:26
