给个两个的样例,举一反三:
\documentclass{ctexart}
\usepackage{calc}
\usepackage{tikz}
\begin{document}
\begin{tabular}{|c|c|p{30pt}|p{30pt}|p{30pt}|}
\hline
\multicolumn{2}{|c|}{%
$\vcenter{\hbox{%
\begin{tikzpicture}
\path[use as bounding box] (\tabcolsep,0) rectangle (4cm-\tabcolsep,1cm);
\draw (0,1cm) -- node[auto]{化验室} node[auto,swap]{} (4cm,0);
\draw (0,1cm) -- node[auto,swap]{} (1.5cm,0);
\end{tikzpicture}%
}}$%
} &\multicolumn{3}{|c|}{室一\quad\quad 室二\quad\quad 室三}\\
\hline
\makebox[1.5cm-2\tabcolsep][c]{aaa} & bbb & ccc &ddd &eee \\
\hline
\end{tabular}
\end{document}
这个例子我看过,感觉它不是“智能”的方案
