I just want to replace the first @{} as @{ \extracolsep{\fill} } show in MWE's comment. When try to use \patchcmd, it failed!

You know, I have a lot of this style table in my document. So want to some automatic code to do this patch work.

Thanks a lot in advance!

MWE:

\documentclass{article}
\usepackage{longtable,booktabs}

\setlength\LTleft{0pt}

\setlength\LTright{0pt}


\begin{document}


\begin{longtable}[]{@{}llll@{}}
%\begin{longtable}[]{@{\extracolsep{\fill}}llll@{}}
\caption{\label{tab:simple-table} A Table}\tabularnewline
\toprule
Name & Income & Job & Color \
\midrule
\endfirsthead
\toprule
Name & Income & Job & Color \
\midrule
\endhead
Jane & 123456 & Research Assistant & red \
John & 50 & N/A & blue \
William & 3200 & Cleaner & blue \
\bottomrule
\end{longtable}


\end{document}

  • it woul be better to change your source than use a tex patch. also it wouldnt matter if you changed them all having two identical settings makes no difference – David Carlisle Sep 10 '22 at 06:19
  • 1)The source .tex is produced from pandoc. 2)Both replace the @{ } as the same @{ \extracolsep{\fill} } also ok, but HOW to do this patch? – user26992 Sep 10 '22 at 08:17
  • you must presumably be specifying somewhere the tabular preamble llll ? (I don't have pandoc installed) – David Carlisle Sep 10 '22 at 08:22
  • I just use pandoc.exe to convert the .markdown to .tex. You know, the other tables may be have different tabular, such as rcclll or cccrrrrrrrrrrrlll, not fixed settings. – user26992 Sep 10 '22 at 08:40

I'm not sure I understand what you're trying to achieve. At any rate, I'd say that in addition to modifying the argument of the \begin{longtable} directive, you should also provide \endfoot and \endlastfoot directives and consider using an S column type for the second column, so that the numbers can be aligned on their respective (implied) decimal markers.

enter image description here

\documentclass{article}
\usepackage{longtable,booktabs,siunitx}

\setlength\LTleft{0pt}

\setlength\LTright{0pt}


\begin{document}


\begin{longtable}{@{\extracolsep{\fill}} 
                  l
                  S[table-format=6.0,group-minimum-digits=4]
                  ll @{}}


%% headers and footers:


\caption{A Table} \label{tab:simple-table} \
\toprule
Name & {Income} & Job & Color \
\midrule
\endfirsthead


\multicolumn{4}{@{}l}{\tablename\ \thetable, continued}\[0.5ex]
\toprule
Name & {Income} & Job & Color \
\midrule
\endhead


\midrule
\multicolumn{4}{r@{}}{\small (continued on following page)} \
\endfoot


\bottomrule
\endlastfoot


%% body of table:


Jane & 123456 & Research Assistant & red \
John & 50 & N/A & blue \
William & 3200 & Cleaner & blue \


\end{longtable}


\end{document}
