我无法消除表格与表格和表格与文本之间的间隙

Question

尽管我付出了长时间的努力，但我还是无法消除表格之间的空格。

我的代码如下：

\documentclass[sigconf, nonacm]{acmart}
\usepackage[all=normal, floats, bibnotes, wordspacing, charwidths, indent, lists]{savetrees}
\usepackage{hyperref}

\makeatletter

\captionsetup{belowskip=0pt}

\belowcaptionskip 0pt

\skip\footins 0.5\baselineskip
\floatsep 0.5\baselineskip
\textfloatsep 0.5\baselineskip
\intextsep 0.5\baselineskip 
\dbltextfloatsep 0.5\baselineskip  
\dblfloatsep 0.5\baselineskip 


\usepackage{longtable}
\setlength\LTpre{0.5\baselineskip}
\setlength\LTpost{0.5\baselineskip}

\usepackage{titlesec}
\titlespacing\section{0pt}{0.5\baselineskip}{0pt}
\titlespacing\subsection{0pt}{0.5\baselineskip}{0pt}
\titlespacing\subsubsection{0pt}{0pt}{0pt}

\raggedbottom

上述代码产生以下输出：

我该如何消除间隙？如您所见，\dbltextfloatsep 0.5\baselineskip不起作用\dblfloatsep 0.5\baselineskip。

Answer 1

尝试一下这个代码。

添加

\captionsetup[table]{position=bottom}
\setlength{\abovecaptionskip}{1ex} % 
\setlength{\belowcaptionskip}{-\baselineskip} 
\addtolength{\belowcaptionskip}{1ex}

设置标题上方和下方的空格。

需要这一行\captionsetup[table]{position=bottom} 是因为 ACM 期刊的风格是：

图表标题必须在图表主体之后输入，表格标题必须在表格主体之前输入。

因此该类使用 相应地设置标题上方和下方的空格\captionsetup[table]{position=top}。
