如何在 Beamer 的标题页中对齐多个作者的姓名、职位和机构？

Question

我必须制作一张有两位作者的幻灯片，这意味着两个人（一个团队）将在演示文稿中展示幻灯片。但是，我无法将团队成员的姓名和角色对齐。

\documentclass{beamer}
\usetheme{Madrid}
\begin{document}
  \title{Cross-Layer  Resource  Allocation with  elastic service scaling in Cloud Radio access network}
  \author{Md.Al-Helal\\SH-51\hspace{3cm}Jobayed Ullah\\EK-107}
\institute{Computer Science \& Engineering}
\begin{frame}
  \maketitle
\end{frame}
  \title{Cross-Layer  Resource  Allocation with  elastic service scaling in Cloud Radio access network}
  \author{Jianhua Tang\\ Wee Pen Tay\\ Tony Q. S. Quek}
\institute{IEEE Transactions on Wireless Communications, vol 14, no. 9}
\date{September 2015}
\begin{frame}
  \maketitle
\end{frame}
\end{document}

Answer 1

用两个parbox-es 写名称。并且不要忘记author在页脚中用您想要的名称填充可选参数。

\documentclass{beamer}
\usetheme{Madrid}
\begin{document}
  \title{Cross-Layer  Resource  Allocation with  elastic service scaling in Cloud Radio access network}
  \author[Md. Al-Helal, Jobayed Ullah]{\parbox{2.5cm}{\centering Md.Al-Helal\\SH-51}\hspace{1cm}\parbox{2.5cm}{\centering Jobayed Ullah\\EK-107}}
\institute{Computer Science \& Engineering}
\begin{frame}
  \maketitle
\end{frame}
  \title{Cross-Layer  Resource  Allocation with  elastic service scaling in Cloud Radio access network}
  \author{Jianhua Tang\\ Wee Pen Tay\\ Tony Q. S. Quek}

\end{document}

Answer 2

堆叠！该stackengine包允许垂直堆叠多个项目，项目之间可以有恒定间隙（短堆叠）或有恒定基线跳跃（长堆叠）。它们可以堆叠，以便最后一个项目位于基线上（堆叠）或第一个项目位于基线上（下堆叠）或围绕基线居中（中心堆叠）。在堆叠中，可以有左、右或中心水平对齐，默认为中心。
