LaTex 表格问题

表格问题1************************************************************************

合并表格后，合并单元格的下面三行不能平均分配列，如图所示：



源代码是：

\begin{table}[htbp]
\centering
\begin{tabular}{|l|c|c|c|c|c|c|}
\hline
\multirow{2}{*}{\textbf{Model}} & \multicolumn{3}{|c|}{\textbf{Trigger Boundary(\%)}} & \multicolumn{3}{|c|}{\textbf{Trigger Boundary + Type(\%)}} \\
\cline{2-7}
& P & R & F & P & R & F \\
\hline
\textit{Single-word} & 55 & 55 & 55 & 55 &  55 & 55 \\
\hline
\textit{Multi-word} & 55 & 55 & 55 & 55 & 55 & 55\\
\hline
\textit{All} & 55 & 55 & 55 & 55 & 55 & 55 \\
\hline
\end{tabular}
\caption{Number of words in triggers}
\label{event:triggerNum}
\end{table}

表格宽度分配不均匀，所以需要指定列的宽度，代码如下：

\begin{table}[htbp]
\centering
\begin{tabular}{|p{2cm}|p{1cm}|p{1cm}|p{1cm}|p{1.2cm}|p{1.2cm}<{\centering}|p{1.2cm}<{\centering}|}
\hline
\multirow{2}{*}{\textbf{Model}} & \multicolumn{3}{|c|}{\textbf{Trigger Boundary(\%)}} & \multicolumn{3}{|c|}{\textbf{Trigger Boundary + Type(\%)}} \\
\cline{2-7}
& P & R & F & P & R & F \\
\hline
\textit{Single-word} & 55 & 55 & 55 & 55 &  55 & 55 \\
\hline
\textit{Multi-word} & 55 & 55 & 55 & 55 & 55 & 55\\
\hline
\textit{All} & 55 & 55 & 55 & 55 & 55 & 55 \\
\hline
\end{tabular}
\caption{Number of words in triggers}
\label{event:triggerNum}
\end{table}

代码运行后的结果是：



由此又产生了另外一个问题，即单元格中的文字没有句中：

需要将代码改为：

\begin{tabular}{|p{3cm}<{\centering}|p{1cm}<{\centering}|p{1cm}<{\centering}|p{1cm}<{\centering}|p{1.2cm}<{\centering}|p{1.2cm}<{\centering}|p{1.2cm}<{\centering}|}

问题完美解决。

效果如果显示：



此处再给出一个复杂点的表格源码：

\begin{table*}
\newcommand{\tabincell}[2]{\begin{tabular}{@{}#1@{}}#2\end{tabular}}
\small
\begin{tabular}{|p{2cm}<{\centering}|p{2cm}<{\centering}|p{2cm}<{\centering}|p{2cm}<{\centering}|p{2cm}<{\centering}|p{2cm}<{\centering}|p{2cm}<{\centering}|}

Overall   & 210 & 900 & 900 & 900 & 900 & 900 \\
\hline
\end{tabular}
\caption{different feature compare}
\label{diffFeatureCompare}
\end{table*}

可以使用 diagbox 宏包，基本语法格式是：

\diagbox[选项]{左}{右}

\diagbox[选项]{左}{中}{右}

\diagbox[dir=⟨方向⟩]{A}{B}

这个表头可以由以下命令实现：

\diagbox[dir=SE]{A}{B}{C}

调用宏包后，直接把上面命令放在 tabular 环境里的对应位置即可。
