如何从顶部排列图形/表格

Question

如何从顶部开始排列图形/表格并使其彼此靠近。

以下是测试代码：

\documentclass[12pt]{article}

\begin{document}

\begin{figure}
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{figure}

\begin{table}
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{table}

\begin{figure}
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{figure}

\end{document}

现在我得到：

我想：

Answer 1

这是一个可能的解决方案。为具有标题功能的图形和表格定义一个新环境。

\makeatletter
\newenvironment{figurehere}  % other name for table, say tablehere
{\def\@captype{figure}}      % for table, replace figure for table
{}
\makeatother

代码

\documentclass[12pt]{article}
\makeatletter
\newenvironment{figurehere}
{\def\@captype{figure}}
{}

\newenvironment{tablehere}
{\def\@captype{table}}
{}
\makeatother

\begin{document}

\begin{figurehere}
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{figurehere}

\begin{tablehere}
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{tablehere}

\begin{figurehere}
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{figurehere}

\end{document}

Answer 2

如果我理解您的设置正确的话，这三个浮动元素将放置在仅浮动元素的页面上。如果是这种情况，您可以继续 (i) 重新定义长度参数\@fptop和 (ii) 使用浮动元素的[t]位置[h]说明符。

在下面的例子中，细线是通过包showframe的选项绘制的geometry。

\documentclass[12pt]{article}
\makeatletter % use this instruction b/c "\@fptop"  contains a "special" character
\setlength{\@fptop}{0pt} % in floats-only pages, don't insert `vfill` at the top
\makeatother
\usepackage[showframe]{geometry} % just for this example
\begin{document}

\begin{figure}[t]
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{figure}

\begin{table}[h]
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{table}

\begin{figure}[h]
\caption{A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!A very long caption!}
\end{figure}
\end{document}
