帮助在 tikz 中分割矩形

我想画一些类似下图的东西。我尝试了 split tikz 库，并尝试分割一个矩形，但没有绘制 32 个部分，它只显示一些部分。

关于如何在乳胶中绘制图片，有什么帮助吗？

谢谢。图片

这是一个简单的例子，使用\pic矩形和编号颜色来使代码简洁。

\documentclass[tikz,border=2mm]{standalone}

% colors
\definecolor{color0}{HTML}{999999} % gray
\definecolor{color1}{HTML}{FF0000} % red
\definecolor{color2}{HTML}{0000FF} % blue
\definecolor{color3}{HTML}{00FF00} % green
\definecolor{color4}{HTML}{FF9999} % light red
 
\tikzset
{
  pics/my rectangle/.style={% #1 -> list of numbers (colors)
    code={%
      \foreach[count=\j]\i in {#1}
        \fill[color\i] (0.2*\j,0) rectangle (0.2*\j+0.18,0.5); 
      \coordinate (-label) at (3.39,-0.3);
      }},
}

\begin{document}
\begin{tikzpicture}
  \pic  (A) at (0,0) {my rectangle={0,0,1,1,1,2,2,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}};
  \node at (A-label) {$0-31$};
  \pic  (B) at (8,0) {my rectangle={0,0,0,0,0,0,0,3,0,0,0,0,0,0,0,1,4,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}};
  \node at (B-label) {$32-63$};
\end{tikzpicture}
\end{document}

matrix一种具有和.list覆盖内腔细胞的替代结构。

\documentclass[tikz, border=1cm]{standalone}
\usetikzlibrary{matrix, positioning, fit}

\colorlet{color0}{gray}
\colorlet{color1}{red}
\colorlet{color2}{blue}
\colorlet{color3}{green}
\colorlet{color4}{pink}


\begin{document}
\begin{tikzpicture}[
    mymatrix/.style={matrix of nodes, nodes in empty cells, inner sep=0mm,
        nodes={fill=color0, anchor=center, minimum width=2mm, 
                minimum height=5mm, inner sep=0pt, outer sep=0pt},
        column sep=.25mm,
        },
    col1/.style={column #1/.style={nodes={fill=color1}}},      
    col2/.style={column #1/.style={nodes={fill=color2}}},
