问题
Is there any obvious or pretty way to have LaTeX automatically put a \hline between each line in a table without having to put a \hline between each line?
I thought about creating a command like:
\newcommand{\EOL}{\\ \hline}
But then I will get non-standard looking tables like this:
3 & 2 & 1 \EOL
1 & 2 & 3 \EOL
Is there a way such that my table bodies could look like:
3 & 2 & 1 \\
1 & 2 & 3 \\
And yet still get the hlines?
回答1:
\catcode`@=11
\let \savecr \@tabularcr
\def\@tabularcr{\savecr\hline}
\catcode`@=12
\begin{tabular}{ccc}
1 & 2 & 3\\
4 & 5 & 6\\
\end{tabular}
