I found that in MathJax, it's supported the following:

\begin{array}{c:c}
 A & B
\end{array}

to produce an array with dashed vertical line.

However, in LaTeX's standard code, the : delimiter isn't provided by amsmath and array, but some packages like arydshln and nicematrix.

The documentation of mathJaX provide that here:

But in the extension list pre-provided by mathjax, it seemed to be no package that provide the : feature.

My Question:

What package extension of mathJaX that provide the feature of the : delimiter for array environment?
