tikz：矩阵内矩形分割中的文本

Question

我有一个tikz matrix，其中一些单元格是矩形分割的，我如何在的两个部分中设置文本rectangle split？

这是 MWE。我希望在矩形分割的两个部分都包含文本...

}
\matrix(m)[matrix of nodes,ampersand replacement=\&,mstyle]{

    0 \& 4 \& 5 \& 0 \& 0 \& 0 \\
    0 \& 0 \& 0 \& 6 \& 0 \& 7 \\
    0 \& 8 \& 10 \& 0 \& 11 \& 0 \\
};
\draw[line] (m-4-5.center) -- (m-3-4.center);
\draw[line] (m-1-6.center) -- (m-3-6.center);
\draw[line] (m-2-2.center) -- (m-4-1.center);
\end{tikzpicture}
\end{figure}

\end{document}

只是为了说清楚。我想在红色圆圈处添加文本。我可以使用这种矩阵方法吗？

您必须直接在节点内部应用分割。

\documentclass{article}

\usepackage{tikz}
\usetikzlibrary{shapes.geometric,matrix,fit,shapes,backgrounds}

\begin{document}

\begin{figure}[htb]
\centering
\begin{tikzpicture}
\tikzset{
    status/.style={draw=black, minimum width=2em, minimum height=2em, text=gray, anchor=center},
    mstyle/.style={nodes={status}, column sep=0.12em, row sep=0.12em},
    splitstyle/.style={inner sep=0.23em,rectangle split, rectangle split horizontal, rectangle split parts=2,rectangle split every empty part={}, rectangle split empty part width={0.3em},  anchor=center},
    line/.style={draw,ultra thick,-latex},
    row 2 column 2/.style={nodes={fill=green}},
    %row 1 column 3/.style={nodes={splitstyle, rectangle split part fill={green,orange}}},
    row 2 column 3/.style={nodes={fill=green}},
    %row 4 column 2/.style={nodes={splitstyle, rectangle split part fill={red,green}}},
    row 3 column 6/.style={nodes={fill=green}},
    row 4 column 3/.style={nodes={fill=orange}},
    row 4 column 5/.style={nodes={fill=orange}},
    row 3 column 4/.style={nodes={fill=red}},
    row 1 column 6/.style={nodes={fill=red}},
}
\matrix(m)[matrix of nodes,ampersand replacement=\&,mstyle]{
    0 \& 0 \& |[splitstyle,rectangle split part fill={green,orange}]| 0\nodepart{two}8  \& 0 \& 0 \& 3 \\
    0 \& 4 \& 5 \& 0 \& 0 \& 0 \\
    0 \& 0 \& 0 \& 6 \& 0 \& 7 \\
    0 \& |[splitstyle,rectangle split part fill={orange,green}]| 8\nodepart{two}0 \& 10 \& 0 \& 11 \& 0 \\
};
\draw[line] (m-4-5.center) -- (m-3-4.center);
\draw[line] (m-1-6.center) -- (m-3-6.center);
\draw[line] (m-2-2.center) -- (m-4-1.center);
\end{tikzpicture}
\end{figure}
