多行表中的中心文本

Question

我从 LaTeX 开始，并在在线表格生成器的帮助下生成了下表。但是，我对某些单元格内容的居中存在一些问题。

这是我的代码：

\usepackage{multirow}
\usepackage{amsmath,amssymb,amsfonts}
\usepackage{algorithmic}

感谢您的帮助。

Answer 1

我建议你们采取以下措施：

• 使表格看起来更加开放，主要是通过省略所有垂直线并使用更少但间隔良好的水平线。（后者可以通过加载包booktabs并使用其宏来实现\toprule，\midrule等。）我

• 使用tabularx环境并让第一列根据需要自动在单元格中插入换行符

• c对所有十个数据列使用基本列类型

• 不要粗体所有标题单元格，除非你迫切需要叫喊在你的读者

• 设置\setlength\tabcolsep{4.5pt}为避免第一列的文本换行

• \vec{...}用。。。来代替\overset{\longrightarrow}{...}。

结果表如下所示：

我想说的是，通过给表格一个更开放的外观，某些单元格“看起来居中”的问题或多或少会自动消失。

Answer 2

这是我想要调整的表格：

修改后的代码如下：

\begin{table*}
\setlength\tabcolsep{4.5pt}
\caption{Nodes closeness centrality}\label{tab3}
\begin{tabularx}{\textwidth}{@{} X *{12}{c} @{}}
\toprule
& \multicolumn{2}{c@{}}{Digital subsystems} 
& \multicolumn{5}{c@{}}{Physical subsystems} 
& \multicolumn{5}{c@{}}{System variables}\\
\cmidrule(l){2-3} \cmidrule(l){4-8} \cmidrule(l){9-13}
\addlinespace
Node & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\
\addlinespace
Node & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \\
\bottomrule
\end{tabularx}
\end{table*}
