\hline not working after \cr

[psymonmarkrine]

• \\ is OK

\begin{array}{}
  a & b \\ \hline
  c & d
\end{array}

• \newline makes a parsing error

\begin{array}{}
  a & b \newline \hline
  c & d
\end{array}

\newline \hline does not work in LaTeX, either.

Since KaTeX emulates LaTeX, this really doesn't qualify as a bug. I'm not sure why \newline works at all. It doesn't work in LaTeX.

I had mistakenly thought that \newline could be substituted for \\ until now.
Thank you for correcting my mistake.

Moreover, may I confirm one more thing?
I checked with Overleaf and indeed \newline does not work in an array environment.
However, \cr \hline work in LaTeX.

\cr \hline does not work in KaTeX.

Does this qualify as a bug?

[ronkok]

Yep, that's a bug. I'll look into it. It may be a few days before I get there.
