tikz 矩阵内的表格

Question

矩阵布局不正确。它应该是 2x3 矩阵。代码有什么问题？

梅威瑟：

\documentclass{article}

\usepackage[table]{xcolor}

\usepackage{tikz}
\usetikzlibrary{matrix}

\begin{document}

\newcommand{\agente}[3] {  % \belongs
\node[draw,inner sep=0] {
    \tabcolsep=0cm
    \begin{tabular}{m{1em}m{1em}}
    #1 & #2 \\
    #3 & \\
    \end{tabular}
}; \\
}
\def\semagente{\agente{}{}{}}

\begin{figure}[htb]
\centering
\begin{tikzpicture}
\tikzset{
}
\matrix[ampersand replacement=\&]{
    \semagente \& \agente{\cellcolor{green} 5}{\cellcolor{orange} 2}{\cellcolor{red} 1} \& \semagente \\
    \semagente \& \agente{\cellcolor{green} 5}{\cellcolor{orange} 2}{\cellcolor{red} 1} \& \semagente \\
};
\end{tikzpicture}
\end{figure}

\end{document}

附言：如果你知道更好的方法将 2x2 矩阵放在像这样的大矩阵中，也请告诉我 :P

\\删除节点结束分号后多余的部分就可以了
