未定义控制序列，table\resizebox

Question

我有下表：

\begin{table}[ht]
\centering
\resizebox{\linewidth}{!}{%
\begin{tabular}{|l|c|c|l|l|l|l|}
\hline
\multirow{2}{*}{\textbf{}} & \multicolumn{6}{c|}{\textbf{Metric}} \\ \cline{2-7} 
 & \multicolumn{3}{c|}{\textbf{SSIM}} & \multicolumn{3}{c|}{\textbf{IoU/F1}} \\ \hline
\textbf{Model} & \multicolumn{1}{l|}{\textbf{Max.}} & \multicolumn{1}{l|}{\textbf{Mean}} & \textbf{Min.} & \textbf{Max.} & \textbf{Mean} & \textbf{Min.} \\ \hline
\textbf{EfficientNetB7} & \textbf{0.956} & \textbf{0.877} & \textbf{0.761} & \textbf{0.988} & \textbf{0.952} & \textbf{0.897} \\ \hline
InceptionV3 & 0.944 & 0.863 & 0.758 & 0.977 & 0.947 & 0.894 \\ \hline
InceptionResNetV2 & 0.941 & 0.859 & 0.743 & 0.983 & 0.943 & 0.886 \\ \hline
DenseNet201 & 0.940 & 0.862 & 0.747 & 0.978 & 0.945 & 0.891 \\ \hline
\end{tabular}
}
\caption{Evaluation of the state-of-the-art models. EfficientNetB7 is proven to be the most suitable model with a high SSIM and IoU score.}
\label{tab:evaluation_models}
\end{table}

编译时出现错误：

Undefined control sequence

The compiler is having trouble understanding a command you have used. Check that the command is spelled correctly. If the command is part of a package, make sure you have included the package in your preamble using \usepackage{...}.

<recently read> \multirow 
                          
l.509 }
       
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

我想问一下是不是我的文档有问题，或者是表格有问题？

提前致谢。

Answer 1

您收到的错误消息通知您\multirow未定义。很可能是因为您没有加载包multirow。

在这种特殊情况下，由于此特定列是空的，因此您也可以完全省略\multirow{2}{*}{\textbf{}}。

除了前面提到的两种消除错误消息的解决方案之外，此表还存在其他问题。使用 intresizebox以确保表的宽度与文本宽度一样，会扭曲字体大小，从而导致整个文档中出现大量不同且不一致的字体大小。由于您的表足够窄，不会溢出到边距，因此只需省略整个表，\resizebox您就会得到以下可编译的示例代码：

\documentclass{article}


\begin{document}

\begin{table}[ht]
\centering
\begin{tabular}{|l|c|c|l|l|l|l|}
\hline
& \multicolumn{6}{c|}{\textbf{Metric}} \\ \cline{2-7} 
 & \multicolumn{3}{c|}{\textbf{SSIM}} & \multicolumn{3}{c|}{\textbf{IoU/F1}} \\ \hline
\textbf{Model} & \multicolumn{1}{l|}{\textbf{Max.}} & \multicolumn{1}{l|}{\textbf{Mean}} & \textbf{Min.} & \textbf{Max.} & \textbf{Mean} & \textbf{Min.} \\ \hline
\textbf{EfficientNetB7} & \textbf{0.956} & \textbf{0.877} & \textbf{0.761} & \textbf{0.988} & \textbf{0.952} & \textbf{0.897} \\ \hline
InceptionV3 & 0.944 & 0.863 & 0.758 & 0.977 & 0.947 & 0.894 \\ \hline
InceptionResNetV2 & 0.941 & 0.859 & 0.743 & 0.983 & 0.943 & 0.886 \\ \hline
DenseNet201 & 0.940 & 0.862 & 0.747 & 0.978 & 0.945 & 0.891 \\ \hline
\end{tabular}
\caption{Evaluation of the state-of-the-art models. EfficientNetB7 is proven to be the most suitable model with a high SSIM and IoU score.}
\label{tab:evaluation_models}
\end{table}

\end{document}

就我个人而言，我建议使用不同的方法，省略所有垂直线和大多数水平线，用booktabs包中的线替换少数有用的水平线，以改善间距，同时摆脱命令\textbf。突出显示所有列标题在这里似乎没有意义。为了使单元格内的数字与小数点对齐，我还使用了包S中的列类型siunitx。（对于这个特定的表格，简单的c列也可以很好地工作）。您还可以将此方法与tabular*以下情况结合使用：您仍然想确保表格的宽度与文本宽度相同，同时不扭曲字体大小：

\documentclass{article}

\usepackage{booktabs}
\usepackage{siunitx}
