Cannot export if Latex uses cases #1950

Open tlegoc opened 1 year ago

tlegoc commented 1 year ago

Hi, The title says it all, I have some latex in my document written like this (not pretty I know) :

$$\begin{cases}
&& 2x_2 &&& + &x_4 & = & 0 \\
2x_1 & + & 2x_2 & + & 3x_3 & + & 2x_4 & = & -2 \\
4x_1 & - & 3x_2 &&& + & x_4 & = & -7 \\
6x_1 & + & x_2 & - & 6x_3 & - & 5x_4 & = & 6
\end{cases}$$

It renders fine on preview but when exporting it to PDF with jupyterlab or vscode gives me this error :

Any idea what's causing this ?
tuncbkose commented 1 year ago

I am not really sure, but I thought that cases is intended to have two columns, so xelatex is complaining that there are more columns than it expects. If this is indeed the case, I have no idea why the preview would work correctly, but I think there is no nbconvert issue here. Maybe this is helpful.
