如何使表格的列标题变为多行？

Question

以下代码：

\documentclass{article}
\usepackage[utf8]{inputenc}
\begin{document}

\begin{table}[t]
\caption{Practically Used Deep CNN Networks}
\label{table1}
\begin{center}
\begin{tabular}{c|c|c|c|c}
NET WIT DATASET  &  CNN layer  &  in a network  &  combining from 2 networks  &  combining from 3 networks
\\ \hline \\
LeNet   MNIST            &  conv1       &  20       &   15      &   15 \\
LeNet MNIST            &  conv2     &  50       &  59       &   59 \\
AlexNet CIFAR10 &conv1      &24     &15     &16 \\
AlexNet CIFAR10 &conv2      &96     &107        &107 \\
\end{tabular}
\end{center}
\end{table}

\end{document}

如何让列标题变为多行？

Answer 1

在这里，我定义了一个新命令\thead，它将标题括在嵌套的tabulars 中。您必须手动换行。我还添加了一些字体命令，只是为了说明您必须在哪里添加命令来影响标题的所有部分。

另外，我建议你加载包大批，并为行添加一些额外的空间。

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{array}
\setlength{\extrarowheight}{2pt} % Add space to rows

\newcommand{\thead}[1]{\small\bfseries\begin{tabular}{@{}c@{}}#1\end{tabular}}

\begin{document}

\begin{table}[t]
\caption{Practically Used Deep CNN Networks}
\label{table1}
\begin{center}
\begin{tabular}{@{}c|c|c|c|c@{}}
\thead{NET WIT\\DATASET}  &  \thead{CNN\\layer}  &  \thead{in a\\network}  &  \thead{combining\\ from\\2 networks } &  \thead{combining\\from\\3 networks}
\\ \hline
LeNet MNIST             &  conv1 & 20  &  15 &   15 \\
LeNet MNIST             &  conv2 & 50  &  59 &   59 \\
AlexNet CIFAR10         &  conv1 & 24  &  15 &   16 \\
AlexNet CIFAR10         &  conv2 & 96  & 107 &  107 \\
\end{tabular}
\end{center}
\end{table}

\end{document}

Answer 2

我建议您采用一个tabularx环境并允许在第 1、4 和 5 列中换行。

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{tabularx}
\newcolumntype{C}{>{\centering\arraybackslash}X}
\newcolumntype{P}[1]{>{\raggedright\arraybackslash}p{#1}}
\newlength\mylen
\settowidth\mylen{AlexNet CIFAR10} % measure width of 1st col.
\begin{document}

\begin{table}[t]
\caption{Practically Used Deep CNN Networks}
\label{table1}
\medskip
\begin{tabularx}{\textwidth}{@{} P{\mylen}|c|c|C|C @{}}
NET WIT DATASET  &  CNN layer  &  In a network  &  Combining from 2 networks  &  Combining from 3 networks\\ 
\hline 
LeNet MNIST     &conv1   &  20     &  15   &   15 \\
LeNet MNIST     &conv2   &  50     &  59   &   59 \\
AlexNet CIFAR10 &conv1   &  24     &  15   &   16 \\
AlexNet CIFAR10 &conv2   &  96     & 107   &  107 \\
\end{tabularx}
\end{table}
\end{document}
