Latex 表格在末尾插入新行

Question

我正在创建两个表，但不知何故，这两个表之间有一行空行。

\begin{table}[!htb]
\begin{center}
\captionof{table}{Properties of the magnetic Resolver}\label{tab:resvprop}
\begin{tabular}{|c|c|}
\hline
\textbf{Parameter} &      \textbf{Value}\\
\hline
Maximum amplitude of the excitation voltage        &       9.0V \\
Excitation frequency  &       10kHz \\   
Number of Pole pairs          &       4 \\
\hline
\end{tabular}
\end{center}
\end{table}


\begin{table}[!htb]
\begin{center}
\captionof{table}{Properties of the Reference Encoder}\label{tab:Encprop}
\begin{tabular}{|c|c|}
\hline
\textbf{Parameter} &      \textbf{Value}\\
\hline
Pulses per Revolution/ Line count      &       1024 \\
Output signals    &       Sine, Cosine \\   
Output signal amplitude          &       1.0V\\
Accuracy         &       \pm 0.0176\textdegree  \\
Power supply               &       DC 5\pm 0.5 V\\
\hline
\end{tabular}
\end{center}
\end{table}

我怎样才能删除两个表格之间的空白区域？

Answer 1

空间过剩是由于两个因素

1. center增加垂直空间；改用\centering；
2. 两个连续的浮点数之间隔着 的量\floatsep。

下面介绍了如何减少它，同时仍然保持单独的浮点数。

\documentclass{article}
\usepackage{siunitx}

\sisetup{separate-uncertainty}

\begin{document}

\begin{table}[!htb]
\centering
\caption{Properties of the magnetic Resolver}\label{tab:resvprop}

\begin{tabular}{|l|c|}
\hline
\multicolumn{1}{|c|}{\textbf{Parameter}} & \textbf{Value}\\
\hline
Maximum amplitude of the excitation voltage & \SI{9.0}{\volt} \\
Excitation frequency                        & \SI{10}{\kilo\hertz} \\
Number of Pole pairs                        & 4 \\
\hline
\end{tabular}

\end{table}


\begin{table}[!htb]
\centering
\caption{Properties of the Reference Encoder}\label{tab:Encprop}

\begin{tabular}{|l|c|}
\hline
\multicolumn{1}{|c|}{\textbf{Parameter}} & \textbf{Value}\\
\hline
Pulses per Revolution/Line count & 1024 \\
Output signals                   & Sine, Cosine \\   
Output signal amplitude          & \SI{1.0}{\volt} \\
Accuracy                         & \SI{\pm 0.0176}{\degree} \\
Power supply                     & DC \SI{5\pm 0.5}{\volt} \\
\hline
\end{tabular}

\end{table}

\end{document}

我使用siunitx这个命令来获得正确的测量值及其单位的输出。我还将第一列的对齐方式改为向左对齐。

不过，您可能更喜欢使用单一table环境。在这里，我还修改了表格代码，以获得更好的外观。但是，如果您愿意，您可以采纳这个想法并保留笼状表格。

\documentclass{article}
\usepackage{siunitx}
\usepackage{booktabs}

\sisetup{separate-uncertainty}

\AtBeginEnvironment{table}{%
  \setlength{\belowcaptionskip}{\medskipamount}
  \setlength{\abovecaptionskip}{0pt}%
}

\begin{document}

\begin{table}[!htb]
\centering
\caption{Properties of the magnetic Resolver}\label{tab:resvprop}

\begin{tabular}{@{}lc@{}}
\toprule
\multicolumn{1}{c}{Parameter} & Value \\
\midrule
Maximum amplitude of the excitation voltage & \SI{9.0}{\volt} \\
Excitation frequency                        & \SI{10}{\kilo\hertz} \\
Number of Pole pairs                        & 4 \\
\bottomrule
\end{tabular}
