When I tried to type table between \between \end blocks, for example
\begin{pmatrix}
\* table contents *\
\end{pmatrix}

The table contents are not recognized. For instance, I can't use Tab to
go to next line. It turns out the result of org-at-table-p is nil. I
deleted all my configurations, but it doesn't get recognized as well.
I'm quite new to emacs, and I can't figure out why. Any instructions on
solving the problem or how to debug is appreciated. Thanks for your assistance!
