多列导致表格格式不正确

我正在尝试在乳胶中绘制一个表格。以下是代码

    \begin{table}[H]
\centering
\caption{Objective Measures for the Quality of Reconstructed Videos using NITRA, OMP and STOMP}
\noindent\resizebox{\textwidth}{!}{\begin{tabular}{@{}cccc|cccc}
        \hline
        \multicolumn{4}{c|}{Averaged total runtime (s) of different algorithms for images } & \multicolumn{4}{c}{Averaged total runtime (s) of different algorithms for videos} \\
        NITRA & CoSaMP & OMP & StOMP & NITRA & CoSaMP & OMP & StOMP\\
        \hline
        1.3067 & 2.5134 & 11.8195 & 19.5301 & 10.4523 & 14.7223 & 73.2695 & 124.7040 \\
        \hline
\label{run}
\end{tabular}}
    \end{table}

我得到的表格如下：在此处输入图片描述

子标题“NITRA 等”未正确对齐。此外，标题“平均总数......”应采用两行格式，以便于阅读。我该怎么做？

答案1

\resizebox如果可以的话，请尽量避免，在这种情况下，您就这样做吧。

使用一行来存储公共信息，使用另一行来存储附加位；这样就\cmidrule可以看出受影响的列是什么。

使用可以获得更好的外观；根据您的特定值siunitx设置数字。table-format

\addtolength我首先使用默认值排版表格\tabcolsep，然后将超出的部分除以 14（列间距数），从而计算出长度。如果收缩过多（我认为超过 4pt），\small请先插入\begin{tabular}并重试。在特别困难的情况下，\footnotesize应该可以解决问题。较小的字体大小会使表格难以阅读，您应该重新考虑如何呈现它。

\documentclass{article}
\usepackage{booktabs,siunitx}
\begin{document}

\begin{table}[htp]
\centering

\caption{Objective Measures for the Quality of Reconstructed
  Videos using NITRA, OMP and STOMP}\label{run}

\addtolength\tabcolsep{-1.5pt}
\begin{tabular}{

  S[table-format=1.4]

  S[table-format=2.4]

例如，如果数据只有一行，则最好以不同的方式组织表格。

\documentclass{article}
\usepackage{booktabs,siunitx}
\begin{document}

\begin{table}[htp]
\centering
\caption{Objective Measures for the Quality of Reconstructed
  Videos using NITRA, OMP and STOMP}\label{run}

\addtolength\tabcolsep{-1.5pt}
\begin{tabular}{
  @{}
  l
  S[table-format=2.4]
  S[table-format=3.4]
  @{}
}
\toprule
\multicolumn{3}{l}{Averaged total runtime (in \si{\second})} \\
\multicolumn{3}{l}{of different algorithms} \\
\midrule
& {images} & {videos} \\
\midrule
NITRA  &  1.3067 &  10.4523 \\
CoSaMP &  2.5134 &  14.7223 \\
OMP    & 11.8195 &  73.2695 \\
StOMP  & 19.5301 & 124.7040 \\
\bottomrule
\end{tabular}

\end{table}

检查一下：

\documentclass{article}
\begin{document}
\begin{table}[H]
\centering
\caption{Objective Measures for the Quality of Reconstructed Videos using NITRA, OMP and STOMP}
\noindent\begin{tabular}{@{}cccc|cccc@{}}
        \hline
        \multicolumn{4}{c|}{\parbox{.4\textwidth}{Averaged total runtime (s) of different algorithms for images }} & \multicolumn{4}{c}{\parbox{.4\textwidth}{Averaged total runtime (s) of different algorithms for videos}} \\
        NITRA & CoSaMP & OMP & StOMP & NITRA & CoSaMP & OMP & StOMP\\
        \hline
        1.3067 & 2.5134 & 11.8195 & 19.5301 & 10.4523 & 14.7223 & 73.2695 & 124.7040 \\
        \hline
\label{run}
\end{tabular}
    \end{table}

另一种方法是使用booktabs

\documentclass{article}
\usepackage{float,booktabs}
\begin{document}
\begin{table}[H]
\centering
\begin{tabular}{cccc|cccc}
\toprule
        \multicolumn{4}{c|}{\parbox{.4\textwidth}{Averaged total runtime (s) of different algorithms for images }} 
        & \multicolumn{4}{c}{\parbox{.4\textwidth}{Averaged total runtime (s) of different algorithms for videos}} \\
        \midrule
        NITRA & CoSaMP & OMP & StOMP & NITRA & CoSaMP & OMP & StOMP\\
        \midrule
        1.3067 & 2.5134 & 11.8195 & 19.5301 & 10.4523 & 14.7223 & 73.2695 & 124.7040 \\
\bottomrule
\end{tabular}
\caption{Objective Measures for the Quality of Reconstructed Videos using NITRA, OMP and STOMP}
\end{table}
\end{document}

答案4

我会缩小两个标题的共同部分。此外，不要使用[H]with table，因为 atable是浮动的。如果您希望表格保持在原位，请使用capt-of或caption包来获取标题。如果表格几乎适合页面，您可以通过使用 减少列间距来获得一些空间\setlength\tabcolsep{...}。

\documentclass{article}
\usepackage{booktabs}
\usepackage{capt-of}
\begin{document}
\begin{center}
  \captionof{table}{Objective Measures for the Quality of Reconstructed
    Videos using NITRA, OMP and STOMP}\label{run}
  \setlength\tabcolsep{0.4em}
  \begin{tabular}{@{}cccc|cccc@{}}
    \toprule
    \multicolumn{8}{c}{Averaged total runtime (in s) of different algorithms} \\
    \multicolumn{4}{c|}{for images} 
        & \multicolumn{4}{c}{for videos}\\
    NITRA  & CoSaMP & OMP     & StOMP 
        & NITRA   & CoSaMP  & OMP     & StOMP\\
    \midrule
    1.3067 & 2.5134 & 11.8195 & 19.5301 
        & 10.4523 & 14.7223 & 73.2695 & 124.7040 \\
    \bottomrule
  \end{tabular}
\end{center}
\end{document}
