![tikz-覆盖多列的节点](https://linux22.com/image/250568/tikz-%E8%A6%86%E7%9B%96%E5%A4%9A%E5%88%97%E7%9A%84%E8%8A%82%E7%82%B9.png)
有没有一种简单的方法可以将 TikZ 中矩阵环境中的节点拉伸到多列上?在下面的示例中,我想将第二行中的三个节点合并为一个宽节点。
任何想法?
\documentclass{minimal}
\usepackage{tikz}
\usetikzlibrary{arrows}
\begin{document}
\begin{tikzpicture}
[auto,
mytext/.style={thick, text width=4.5em,inner sep=1pt},
line/.style ={draw, thick, -latex',shorten >=2pt},
block/.style ={rectangle,text width=6em,draw,minimum height=4em, outer sep=0pt}]
\matrix [column sep=1cm,row sep=7mm]
{
% 1. row
\node [mytext] (st0) {Step 1}; &
\node [block] (cl0) [label=above:\textbf{Climate}] {rainfall and temperature}; &
\node [block] (veg0) [label=above:\textbf{Vegetation}] {forest}; &
\node [block] (sol0) [label=above:\textbf{Soil and terrain}]
{soil}; \\
% 2. row
\node (st2) {some text}; &
\node [block] (cl1) {this blocks}; &
\node [block] (veg1) {should be}; &
\node [block] (sol1) {merged together}; \
\\ };
\tikzstyle{every path}=[line]
\path (cl0) -- (cl1);
\path (veg0) -- (veg1);
\path (sol0) -- (sol1);
\end{tikzpicture}
\end{document}

这当然不是最干净的方法,但可能是最简单的
\documentclass{minimal}
\usepackage{tikz}
\usetikzlibrary{arrows,fit}
\begin{document}
\begin{tikzpicture}
[auto,
mytext/.style={thick, text width=4.5em,inner sep=1pt},
line/.style ={draw, thick, -latex',shorten >=2pt},
block/.style ={rectangle,text width=6em,draw,minimum height=4em, outer sep=0pt},
blocka/.style ={rectangle,text width=6em,minimum height=4em, outer sep=0pt}]
\matrix [column sep=1cm,row sep=7mm]
{
% 1. row
\node [mytext] (st0) {Step 1}; &
\node [block] (cl0) [label=above:\textbf{Climate}] {rainfall and temperature}; &
\node [block] (veg0) [label=above:\textbf{Vegetation}] {forest}; &
\node [block] (sol0) [label=above:\textbf{Soil and terrain}]
{soil}; \\
% 2. row
\node (st2) {some text}; &
\node [blocka] (cl1) {}; &
\node [blocka] (veg1) {}; &
\node [blocka] (sol1) {}; \\
\\ };
\tikzstyle{every path}=[line]
\path (cl0) -- (cl1);
\path (veg0) -- (veg1);
\path (sol0) -- (sol1);
\node[block] (outer) [fit=(cl1) (veg1) (sol1)] {this blocks should be merged together};
\end{tikzpicture}
\end{document}
