如何制作合法的两列（或三列）签名组件？

Question

我需要为一份法律文件添加两列或三列结尾，如附图所示。我需要一些帮助来设置它吗？我应该使用某种框或列吗？我需要右括号列和签名相对于左侧列垂直居中。

Answer 1

由于滥用数学模式……

\documentclass{article}

\begin{document}

\begin{center}
$\left.\kern-\nulldelimiterspace
\begin{tabular}{@{}l@{}}
SWORN (OR AFFIRMED) BEFORE ME \\
at Vancouver, in the Province of British Columbia, \\
the 3rd day of March, 2020 \\[2cm]
$\overline{\mbox{\rule{0pt}{2ex}A commissioner for taking Affidavits\ \ }}$\\
or a Notary Public
\end{tabular}
\right\rbrace
\displaystyle\frac{}{\makebox[5cm][l]{\rule{0pt}{2ex}Merry Jane Doe}}
$
\end{center}

\end{document}

Answer 2

这是一个基于 egreg 解决方案的变体

\documentclass{article}

\begin{document}

\begin{center}
$
\begin{tabular}{@{}l@{)}}
SWORN (OR AFFIRMED) BEFORE ME \\
at Vancouver, in the Province of British Columbia, \\
the 3rd day of March, 2020 \\ %[2cm]
\\
\\
\\
$\overline{\mbox{\rule{0pt}{2ex}A commissioner for taking Affidavits\ \ }}$\\
or a Notary Public
\end{tabular}
\displaystyle\frac{}{\makebox[5cm][l]{\rule{0pt}{2ex}Merry Jane Doe}}
$
\end{center}

\end{document}

不同之处在于用作)表格列的“右分隔符” @{)}（加上一些空行）

Answer 3

类似这样的事？

% sigprob.tex SE 531499 Two or thre col signature

\documentclass{article}

\begin{document}
\noindent\begin{tabular}{p{0.5\textwidth}|l} 
SWORN (OR AFFIRMED) at Vancouver more text & \\
                         & Mary Jane Doe \\
A Commissioner more text & \\
\end{tabular}
\end{document}

按需要进行调整。
