LaTeX中的多行多解问题

Question

在使用multicolumn和multirow时，在LaTex上创建表时遇到了问题。这里是我正在使用的代码

\documentclass[12 pt, letterpaper, twoside, openright]{book}

\usepackage{amsmath} 

\usepackage{multirow} 

\usepackage{enumitem}
\usepackage{booktabs, makecell, longtable}
\usepackage{stackengine}
\usepackage{tabularx}
\usepackage{caption}
\usepackage{subcaption}

\usepackage[super]{nth} 

\usepackage{array}
\newcolumntype{P}[1]{>{\centering\arraybackslash}p{#1}}
\usepackage[table]{xcolor}
%http://latexcolor.com/
\definecolor{amber}{rgb}{1.0, 0.75, 0.0} %giallo ocra

\begin{document}

\begin{table}[!b]
\centering
  \begin{tabular}{l|ccc|ccc|ccc}
    \multirow{2}{*}{Periods and Hours} &
      \multicolumn{3}{|c|}{\cellcolor{amber}Total} &
      \multicolumn{3}{|c|}{\cellcolor{amber}First period} &
      \multicolumn{3}{|c}{\cellcolor{amber}Second Period} \\[0.5ex]
      & \cellcolor{amber}hypo & \cellcolor{amber}\cellcolor{amber}normo & \cellcolor{amber}hyper& \cellcolor{amber}hypo & \cellcolor{amber}normo & \cellcolor{amber}hyper& \cellcolor{amber}hypo & \cellcolor{amber}normo & \cellcolor{amber}hyper\\[0.5ex]
    \hline
     \multirow{2}{3em} TIR (\%) PP1 & 54,02 & 14,59 & 31,38 &48,7 &9,48&41,77&59,9&20,29&19,8\\
      Hour(h) & 57 & 15 & 33 &27 &5&23&30&10 &10\\
      \hline
  \end{tabular}
\end{table}

\end{document}

这是输出

我不知道为什么时间和时间都这么混乱。请帮助我：

Answer 1

语法\multirow{2}{3em} TIR (\%) PP1是错误的。\multirow有3个强制参数，最后一个是单元格的内容。因此，如果要合并两个单元格，则需要\multirow{2}{3em}{ TIR (\%) PP1} (请注意单元格内容周围的{...} )。

..。也就是说，下面的单元格已经充满了Hour(h)。如果您希望上面的单元格与此单元合并，则必须将其保留为空。

    \hline
%     \multirow{2}{3em}
     TIR (\%) PP1 & 54,02 & 14,59 & 31,38 &48,7 &9,48&41,77&59,9&20,29&19,8\\
      Hour(h) & 57 & 15 & 33 &27 &5&23&30&10 &10\\
      \hline
  \end{tabular}
\end{table}

\end{document}

就我个人而言，我将使用tabularray包，这使得合并单元格变得非常容易：

\documentclass{book}

\usepackage{xcolor}
\definecolor{amber}{rgb}{1.0, 0.75, 0.0} %giallo ocra
\usepackage{tabularray}

\begin{document}

\begin{table}[htbp]
  \begin{tblr}{
    colspec={l|ccc|ccc|ccc},
    cell{1-2}{2-10} = {amber}
  }
    \SetCell[r=2]{} Periods and Hours &
    \SetCell[c=3]{} Total & & & 
    \SetCell[c=3]{} First period & & &
    \SetCell[c=3]{} Second Period & &\\
    & hypo & normo & hyper& hypo & normo & hyper& hypo & normo & hyper\\
    \hline
     TIR (\%) PP1 & 54,02 & 14,59 & 31,38 &48,7 &9,48&41,77&59,9&20,29&19,8\\
      Hour(h) & 57 & 15 & 33 &27 &5&23&30&10 &10\\
      \hline
  \end{tblr}
\end{table}

\end{document}
