\cals 的使用与其定义 \calscommand 不符

Question

以下最小工作示例cals在文档环境中使用了一个表格，并且运行良好：

\documentclass{article}

%document encoding
\usepackage[utf8]{inputenc}

%geometry
\RequirePackage[a4paper, layoutwidth=10.5cm, layoutheight=20cm, noheadfoot, nomarginpar, margin=0mm, showcrop]{geometry}
\RequirePackage{calc}
\geometry{layouthoffset=0.5\paperwidth-5.25cm}
\geometry{layoutvoffset=0.5\paperheight-10cm}
\setlength{\topskip}{0mm}
\setlength{\parindent}{0mm}

%table
\RequirePackage{cals}

\begin{document}
\thispagestyle{empty}
\begin{calstable}
\makeatletter
\colwidths{{3.30cm}{1.95cm}{5.25cm}}
\def\cals@cs@width{0.8pt}
\def\cals@rs@width{0.8pt}
\setlength{\cals@paddingT}{1.44ex}
\setlength{\cals@paddingL}{1em}
\brow \nullcell{tbl}\nullcell{tb}\nullcell{tbr}\spancontent{} \ht\cals@current@row=30mm \erow
\brow \alignC \nullcell{tbl}\nullcell{tbr}\spancontent{} \alignL \cell{} \ht\cals@current@row=22mm \erow
\makeatother
\end{calstable}
\end{document}

但是，当我将代码放入\newcommand调用中时\calscommand，出现Use of \cals doesn't match its definition \calscommand错误：

\documentclass{article}

%document encoding
\usepackage[utf8]{inputenc}

%geometry
\RequirePackage[a4paper, layoutwidth=10.5cm, layoutheight=20cm, noheadfoot, nomarginpar, margin=0mm, showcrop]{geometry}
\RequirePackage{calc}
\geometry{layouthoffset=0.5\paperwidth-5.25cm}
\geometry{layoutvoffset=0.5\paperheight-10cm}
\setlength{\topskip}{0mm}
\setlength{\parindent}{0mm}

%table
\RequirePackage{cals}
\newcommand{\calscommand}{%
\thispagestyle{empty}
\begin{calstable}
\makeatletter
\colwidths{{3.30cm}{1.95cm}{5.25cm}}
\def\cals@cs@width{0.8pt}
\def\cals@rs@width{0.8pt}
\setlength{\cals@paddingT}{1.44ex}
\setlength{\cals@paddingL}{1em}
\brow \nullcell{tbl}\nullcell{tb}\nullcell{tbr}\spancontent{} \ht\cals@current@row=30mm \erow
\brow \alignC \nullcell{tbl}\nullcell{tbr}\spancontent{} \alignL \cell{} \ht\cals@current@row=22mm \erow
\makeatother
\end{calstable}
}

\begin{document}
\calscommand
\end{document}

我究竟做错了什么？

Answer 1

移动

\makeatletter

在你的定义之前

\makeatother

之后。您需要 @将 用作命令名称中使用的字母，该字母位于您使用这些命令的定义处，而不是定义内部。
