从两列切换到一列而不添加分页符

Question

我正在努力适应此解决方案如下所示，有多位作者和多个附属机构：

                   

改为一种格式，标题和作者在第一页顶部的单列中，但常规文本则分两列。请参阅本文底部的原始模板快照。

我尝试\onecolumn在作者和标题所属之前插入，然后立即切换回\twocolumn，但 LaTeX 在呈现常规文本（摘要等）之前创建了一个完整的分页符。我该如何避免这个分页符？

\documentclass{article}
\usepackage{spconf,amsmath,graphicx}
\usepackage{url}
\usepackage{amssymb}
\usepackage{caption}
\usepackage[labelformat=simple]{subcaption}
\usepackage{calc}
\usepackage{enumitem}
\usepackage{kantlipsum}
\usepackage{array}

\newcommand\Mark[1]{\textsuperscript#1}

\begin{document}
\onecolumn
\begingroup
\centering
{\LARGE The Title \\[1.5em]
\large First Author\Mark{1}, Second Author\Mark{2}, Third Author\Mark{1}, Fourth Author\Mark{2} and Fifth Author\Mark{3}}\\[1em]
\begin{tabular}{*{2}{>{\centering}p{.25\textwidth}}}
\Mark{1}Department1 & \Mark{2}Department2 \tabularnewline
School1 & School2  \tabularnewline
\url{email1} & \url{email2}
\end{tabular}\par
\twocolumn
\endgroup

\begin{abstract}
This text should be back in two columns
\end{abstract}

\end{document}

Answer 1

将标题材料放入可选参数中\twocolumn。在示例中，我仅使用所需的特定包。

唯一要注意的一点是[]代码中多了一对括号。

\documentclass[twocolumn]{article}
\usepackage{array,url,kantlipsum}

% \Mark is probably provided by spconf, that I don't have
\newcommand{\Mark}[1]{\textsuperscript{#1}}

\begin{document}
\twocolumn[{%
 \centering
 \LARGE The Title \\[1.5em]
 \large First Author\Mark{1},
        Second Author\Mark{2},
        Third Author\Mark{1},
        Fourth Author\Mark{2}
    and Fifth Author\Mark{3}\\[1em]
 \normalsize
 \begin{tabular}{*{2}{>{\centering}p{.25\textwidth}}}
  \Mark{1}Department1 & \Mark{2}Department2 \tabularnewline
  School1 & School2  \tabularnewline
  \url{email1} & \url{email2}
 \end{tabular}\\[3em] % some more space after the title part
}]

\begin{abstract}
This text should be back in two columns
\end{abstract}

\section{Introduction}
\kant

\end{document}
