信件中有多个并排签名

Question

scrlttr2我尝试使用签名定义中的环境在信件中添加三个并排签名minipage。我收到错误：Extra }, or forgotten \endgroup指向结束行。如果我不使用 minpages，错误就会消失。这是 MWE：

\documentclass[%
paper=letter,
pagesize,
fontsize=10pt,
standard
]{scrlttr2}

\usepackage{filecontents}
\setkomavar{fromname}{Sender's Name}
\setkomavar{fromaddress}{Some street\\in some town\\with zip code}
\begin{filecontents}{standard.lco}
    \setkomavar{signature}{% 
    \begin{minipage}[b]{0.33\linewidth}
    First name\\
    Position 1
    \end{minipage}
    \begin{minipage}[b]{0.33\linewidth}
    Second name\\
    Position 2
    \end{minipage}
    \begin{minipage}[b]{0.33\linewidth}
    Third name\\
    Position 3
    \end{minipage}
}

\@setplength[1]{sigindent}{0.01\textwidth}
\end{filecontents}


\begin{document}
\begin{letter}{%
Recipient's name,\\
Some position\\
More address info
}

\opening{Dear Recipient}
\lipsum[1-2]

\closing{Sincerely,}

\end{letter}
\end{document}

即使编译失败，文档仍可正确呈现。我这样做对吗？

Answer 1

除了minipages，您还可以使用\parboxes：

\documentclass[%
paper=letter,
pagesize,
fontsize=10pt,
standard
]{scrlttr2}
\usepackage[english]{babel}
\usepackage{lipsum}

\newcommand\Sigline[4][t]{%
  \parbox[#1]{.333\linewidth}{\raggedright#2}%
  \parbox[#1]{.333\linewidth}{\raggedright#3}%
  \parbox[#1]{.333\linewidth}{\raggedright#4}%
}

\setkomavar{fromname}{Sender's Name}
\setkomavar{fromaddress}{Some street\\in some town\\with zip code}
\setkomavar{signature}{% 
   \Sigline{First name}{Second name}{Third name} \\
  \Sigline{Position 1}{Position 2}{Position 3} \\
}

\begin{document}
\begin{letter}{%
Recipient's name,\\
Some position\\
More address info
}

\opening{Dear Recipient}
\lipsum[2]

\closing{Sincerely,}

\end{letter}
\end{document}

Answer 2

这是一个独立于任何特定文档类别的解决方案。

\documentclass{minimal}

\begin{document}

Lorem ipsum dolor sit amet, consetetur sadipscing elitr,
sed diam nonumy eirmod tempor invidunt ut labore
et dolore magna aliquyam erat, sed diam voluptua.

\def\s#1#2{\vbox{\hsize=4.5cm
    \kern2cm
    \hrule\kern1ex
    \hbox to \hsize{\strut\hfil #1 \hfil}
    \hbox to \hsize{\strut\hfil #2 \hfil}}}

\hbox to \hsize{\s{John Doe}{President}\hfil
    \s{Jane Doe}{COO}\hfil
    \s{James Dow}{CFO}} 

\end{document}
