\and command in \author tag
In the standard class the author is printed inside the environment tabular
. Therefor the command \and
is defined as:
\def\and{% % \begin{tabular}
\end{tabular}%
\hskip 1em \@plus.17fil%
\begin{tabular}[t]{c}}% % \end{tabular}
In your case you don't need an extra \and
. You document class puts the author in a center environment. So you can use
\Author{John Doe \\
\texttt{[email protected]}
%\and
\\
Jane Doe \\
\texttt{[email protected]}
}
In article
class \author
command is internally set as a tabular and \and
finishes one tabular and starts another so a list of authors becomes a list of tabulars.
this class just sets Author in a center
environment and doesn't provide a replacement for \and
. You could just use \\
or use
\renewcommand\and{\\[\baselineskip]}
