cals - 删除表格的左侧和右侧边距

Question

我尝试使用卡路里-package，但遇到了问题。我尝试移除侧轴承（通过>@{}使用大批）。据我所知，我必须通过\setlength{\cals@paddingL}{0pt}在第一列的所有最左侧单元格处发出一个来删除最左列的左填充，然后通过\cals@setpadding{Ag}\在该单元格后立即恢复它。右侧也是如此。

这种方法在表格主体中有效，如附图所示。但是，如果我使用标题 ( \thead{<code>}) 中的代码，则代码无法编译。对于随附的 MWE，您会收到错误消息，指示未定义命令。

这是 MWE（MnWE）：

\documentclass{article}
\usepackage{cals}
\begin{document}

\begin{calstable}
\colwidths{{50pt}{100pt}}
%
\thead{\bfseries\selectfont
\brow
    \makeatletter\setlength{\cals@paddingL}{0pt}\makeatother % If you comment out line 16 and 18 the MWE compiles
    \cell{col1}
    \makeatletter\cals@setpadding{Ag}\makeatother % Comment out to compile
    \cell{col2}
\erow
\mdseries\selectfont}
\tfoot{\lastrule\nointerlineskip
\textit{\strut Some table caption
(not implemented: PartKofN)}\par}
%
\brow
    \makeatletter\setlength{\cals@paddingL}{0pt}\makeatother
    \cell{r1,col1}
    \makeatletter\cals@setpadding{Ag}\makeatother
    \makeatletter\setlength{\cals@paddingR}{0pt}\makeatother
    \alignR\cell{r1,col2}
    \makeatletter\cals@setpadding{Ag}\makeatother
 \erow
%
\brow
    \alignL\cell{r2,col1}
    \alignR\cell{r2,col2}
\erow
%
\brow
    \alignL\cell{r3,col1}
    \cell{r3,col2}
\erow
%\tbreak{Manual table break!\strut\par}
\brow
    \cell{r4,col1}
    \cell{r4,col2}
\erow
%
\brow
    \cell{r5,col1}
    \cell{r5,col2}
\erow
\end{calstable}
\end{document}

这是日志文件：

是错误还是用户错误？

Answer 1

Catcode 更改（\makeatletter、\makeatother等）将无法用作宏参数。您正在执行\thead{... \makeatletter\setlength{\cals@paddingL}{0pt}}。这被标记为\makeatletter\setlength{\cals @paddingL}{0pt}（注意 后面的空格\cals）。您需要将\makeatletter和移到\makeatother之外\thead。

您还可以减少一堆\makeatletter<code with @>\makeatother并\makeatletter在所有代码@开始时使用一个，并\makeatother在所有结束时使用一个。

此外，\bfseries已经这样做了\selectfont，因此后者在这里是多余的：

\documentclass{article}
\usepackage{cals}
\begin{document}

\begin{calstable}
\colwidths{{50pt}{100pt}}
%
\makeatletter
\thead{\bfseries
\brow
    \setlength{\cals@paddingL}{0pt}% If you comment out line 16 and 18 the MWE compiles
    \cell{col1}
    \cals@setpadding{Ag}% Comment out to compile
    \cell{col2}
\erow
\mdseries}
\makeatother
\tfoot{\lastrule\nointerlineskip
\textit{\strut Some table caption
(not implemented: PartKofN)}\par}
%
\makeatletter% @=11
\brow
    \setlength{\cals@paddingL}{0pt}%
    \cell{r1,col1}
    \cals@setpadding{Ag}
    \setlength{\cals@paddingR}{0pt}
    \alignR\cell{r1,col2}
    \cals@setpadding{Ag}
\erow
\makeatother% @=12
%
\brow
    \alignL\cell{r2,col1}
    \alignR\cell{r2,col2}
\erow

\brow
    \alignL\cell{r3,col1}
    \cell{r3,col2}
\erow
%\tbreak{Manual table break!\strut\par}

    \cell{r4,col2}
