The Org manual states that LaTeX fragments are Environments of any kind. The only requirement is that the ‘\begin’ statement appears on a new line, preceded by only whitespace.
yet, the Org document #+OPTIONS: tex:dvisvgm \begin{array}{cc|c} P & Q & P \iff Q \\ \hline 0 & 0 & 1 \\ 0 & 1 & 0 \\ 1 & 0 & 0 \\ 1 & 1 & 1 \\ \end{array} exports to HTML with cc|c visible (and a broken array). More generally, LaTeX environments \begin{ENVIRONMENT}{OPTIONS} that include some {OPTIONS} do not export to HTML well.
