如何排版倾斜矩阵？

Question

我需要为我的家庭作业排版类似的东西。怎么做？很抱歉，我没有 MWE，因为我甚至不知道如何开始。另外，我不需要里面的颜色。只要知道如何排版就足够了。

用foreach会更好，但你可以从这个开始

\documentclass[a4paper,11pt]{article}
\usepackage{tikz}
\usetikzlibrary{positioning, shapes}

\begin{document}
\begin{tikzpicture}[mynode/.style={regular polygon, regular polygon sides=4, 
                      minimum size=2cm, shape border rotate=45, draw}]

\node[mynode, label={135:1}, label={-90:$A_1$}] (00) {0};
\node[mynode, above right= -\pgflinewidth of 00, label={135:2}] (01)  {1500};
\node[mynode, above right= -\pgflinewidth of 01, label={135:3}, label={45:1}, label=90:$m$] (02)  {1000};

\node[mynode, below right= -\pgflinewidth of 01, fill=black!30,label={-90:$A_2$}] (10)  {1200};
\node[mynode, above right= -\pgflinewidth of 10] (10)  {1500};

\node[mynode, below right= -\pgflinewidth of 10, fill=black!20, label={-90:$A_3$}] (120)  {0};

\end{tikzpicture}
\end{document}
