签名行上方的空间

Question

我正在尝试制作一个签名块，该签名块在签名行上方有足够的空间来盖章。但指示\vspace似乎没有效果。

如何才能保留上面3cm呢\hline？

\documentclass[a4paper]{article}
\usepackage{tabularx}

\newcommand{\signatureline}[1]{%
  \begin{tabular}{@{}p{6cm}@{}}
    \vspace{3cm} % Increasing this seems to have no effect
    \\ \hline \\[-.75\normalbaselineskip]
    #1
  \end{tabular}
  \hspace{2cm}
  \begin{tabular}{@{}p{4cm}@{}}
    \vspace{3cm} % Increasing this seems to have no effect
    \\ \hline \\[-.75\normalbaselineskip]
    Date
  \end{tabular}
  \\
}

\newcommand{\approval}{%
  \par\vspace*{\fill} % Puts signature lines in the same spot of each page for easy stamping
  \section*{Approvals}
  \signatureline{Operator} % Putting \vspace after this doesn't put space between these signaturelines
  \signatureline{Authority}
  \clearpage
}

\begin{document}
Some text
\approval
\end{document}

Answer 1

使用具有所需高度的不可见物体。

我还添加了\par“\\这不适合这份工作”和\hfill“而不是” \hspace{2cm}。

\documentclass[a4paper]{article}
\usepackage{tabularx}

\newcommand{\signatureline}[1]{%
  \par\noindent
  \begin{tabular}{@{}p{6cm}@{}}
    \rule{0pt}{3cm}
    \\ \hline \\[-.75\normalbaselineskip]
    #1
  \end{tabular}\hfill
  \begin{tabular}{@{}p{4cm}@{}}
    \rule{0pt}{3cm}
    \\ \hline \\[-.75\normalbaselineskip]
    Date
  \end{tabular}\par
}

\newcommand{\approval}{%
  \par\vspace*{\fill} % Puts signature lines in the same spot of each page for easy stamping
  \section*{Approvals}
  \signatureline{Operator} % Putting \vspace after this doesn't put space between these signaturelines
  \signatureline{Authority}
  \clearpage
}

\begin{document}
Some text
\approval
\end{document}

Answer 2

另一个解决方案是将您所做的相同操作添加到 hline。\\[3cm]

\documentclass[a4paper]{article}
\usepackage{tabularx}

\newcommand{\signatureline}[1]{%
  \begin{tabular}{@{}p{6cm}@{}}
   % \vspace{3cm} % Increasing this seems to have no effect
    \\[3cm]
     \hline \\[-.75\normalbaselineskip]
    #1
  \end{tabular}
  \hspace{2cm}
  \begin{tabular}{@{}p{4cm}@{}}
   % \vspace{3cm} % Increasing this seems to have no effect
    \\[3cm]
     \hline \\[-.75\normalbaselineskip]
    Date
  \end{tabular}
  \\
}

\newcommand{\approval}{%
  \par\vspace*{\fill} % Puts signature lines in the same spot of each page for easy stamping
  \section*{Approvals}
  \signatureline{Operator} % Putting \vspace after this doesn't put space between these signaturelines
  \signatureline{Authority}
  \clearpage
}

\begin{document}
Some text
\approval
\end{document}
