tabularx 的布局问题

这是我的fsmpic.cls：

\NeedsTeXFormat{LaTeX2e}
\LoadClass[version=last]{scrlttr2}
\RequirePackage[utf8]{inputenc}
\RequirePackage[T1]{fontenc}
\RequirePackage[ngerman]{babel}
\usepackage[scaled]{helvet}
\renewcommand{\familydefault}{\sfdefault}
\KOMAoption{parskip}{full-}
\RequirePackage[a4paper,]{geometry}
\RequirePackage{tabularx}
\RequirePackage{ltablex}
\RequirePackage{booktabs}

\keepXColumns
\newcolumntype{L}[1]{>{\raggedright\let\newline\\\arraybackslash\hspace{0pt}}p{#1}}
\newcolumntype{R}[1]{>{\raggedleft\let\newline\\\arraybackslash\hspace{0pt}}p{#1}}
\newcolumntype{\L}{>{\raggedright\let\newline\\\arraybackslash\hspace{0pt}}X}
\setlength{\heavyrulewidth}{0.6pt}
\setlength{\lightrulewidth}{0.3pt}
\setlength{\tabcolsep}{1mm}
\renewcommand{\arraystretch}{1.2}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\RequirePackage{environ}

\NewEnviron{MyEnviron}[3]{%
    \newcounter{fsmpic@MyCounter}%
    \begin{tabularx}{\linewidth}{%
            L{15mm}%
            \L%
            L{25mm}%
            L{15mm}%
            R{25mm}%
            R{25mm}%
        }%
        \textbf{A} & \textbf{B} & \textbf{Menge} & \textbf{USt.} & \textbf{Einzelpreis} & \textbf{Summe} \\%
        \toprule\endhead%
        \BODY%
        \midrule%
        \multicolumn{5}{\L}{Some Text} & #1 \\%
        \MyCommand{#2}%
        \bottomrule%
        \multicolumn{5}{\L}{\textbf{More Text}} & \textbf{#3}%
    \end{tabularx}%
}

\ExplSyntaxOn
\NewDocumentCommand{\MyCommand}{ >{ \SplitList {,} } m }
 {
    \ProcessList {#1} {\fsmpic_process_argument:n}
 }
\cs_new_protected:Nn \fsmpic_process_argument:n
 {
  \fsmpic_column:nn #1
 }
 \cs_new_protected:Nn \fsmpic_column:nn
 {
  \multicolumn{5}{\L}{Text #1 Another Text} & #2 \\
  \penalty0
 }
\ExplSyntaxOff

\newcommand{\MySecondCommand}[5]{\stepcounter{fsmpic@MyCounter}\thefsmpic@MyCounter & #1 & #2 & #3 & #4 & #5 \\}

这是我的 tex.tex：

\documentclass[tex]{fsmpic}

\begin{document}
\begin{letter}{}

    \opening{Opening,}

    \begin{MyEnviron}{Number A}{{B}{C},{D}{E}}{F}
        \MySecondCommand{Some Text}{G}{H}{I}{J}
    \end{MyEnviron}

\end{letter}
\end{document}

SplitList 运行良好，但是带有多行的 tabularx 布局\fsmpic_column完全被破坏了。

布局损坏的图片

我究竟做错了什么？

您不应将其用作\L列类型，因为这是一个现有命令。我改用M。

问题是\multicolumn 必须首先（扩展后）出现在表格单元格中，但您的\MyCommand不可扩展。

\ExplSyntaxOn
\NewExpandableDocumentCommand{\MyCommand}{ m }
 {
    \clist_map_function:nN { #1 } \fsmpic_process_argument:n
 }
\cs_new:Nn \fsmpic_process_argument:n
 {
  \fsmpic_column:nn #1
 }
 \cs_new:Nn \fsmpic_column:nn
 {
  \multicolumn{5}{M}{Text #1 Another Text} & #2 \\
 }
\ExplSyntaxOff

顺便说一句，environ已经被认为是过时的了。

\newcounter{fsmpic@MyCounter}

\NewDocumentEnvironment{MyEnviron}{mmm+b}{%
    \setcounter{fsmpic@MyCounter}{0}%
    \begin{tabularx}{\linewidth}{
            L{15mm}
            X
            L{25mm}
            L{15mm}
            R{25mm}
            R{25mm}
        }
        \textbf{A} & \textbf{B} & \textbf{C} & \textbf{D} & \textbf{E} & \textbf{F} \\
        \toprule\endhead
        #4
        \midrule
        \multicolumn{5}{M}{Some Text} & #1 \\
        \MyCommand{#2}
        \bottomrule
        \multicolumn{5}{M}{\textbf{More Text}} & \textbf{#3}
    \end{tabularx}
}{}

当然，\newcounter 必须超出环境的定义。
