我已经知道如何制作表格了，我想知道如何在每个块内放置颜色。我需要一些建议才能开始。
答案1
这是一个您可以参考的示例。我已将宽度为零的 L 列定义为最后一列。在第 3 行至第 7 行中，我放置了一个宽度为零的规则，其高度与第 3 列至第 6 列的列宽相同，以确保单元格为正方形。我还为不同的颜色定义了快捷方式，以减少表格中的混乱。
请随时提问，我会更新答案。：

下面可以作为使用 的起点tikz matrix：
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{fit,matrix}
\begin{document}
\begin{tikzpicture}[cell/.style={rectangle,draw=black}, nodes in empty cells]
\matrix(table)[
matrix of nodes,
row sep =-\pgflinewidth,
column sep = -\pgflinewidth,
nodes={anchor=center,minimum height=1.5cm,minimum width=1.5cm, align=center, text width=1cm, draw=black},
column 1/.style = {nodes={cell, minimum width=0.25cm, fill=white, draw=none, align=right}},
row 1/.style = {nodes={cell, minimum height=0.5cm, fill=none, draw=none, align=center}},
row 6/.style = {nodes={cell, minimum height=0.5cm, fill=none, draw=none, align=center}},
row 7/.style = {nodes={cell, minimum height=0.5cm, fill=none, draw=none, align=center}},
