Question

你能帮我完成这个吗？

梅威瑟：

 \documentclass[tikz,border=7pt]{standalone}

\usetikzlibrary{positioning,arrows.meta}

\usetikzlibrary{shadows.blur,shapes.multipart}
\tikzset{grimsel/.style={rectangle split,rectangle split parts=1,draw,
        fill=gray!20,blur shadow,rounded corners,align=center}}

\begin{document}
  \begin{tikzpicture}[node distance=0mm,minimum height=1cm,outer sep=3mm,scale=0.8,>=Latex,font=\sffamily\footnotesize,
  indication/.style={minimum height=0cm,outer sep=0mm},
  oneblock/.style={transform shape,minimum width=1cm,draw,thick},
  fullset/.style={transform shape,minimum width=10cm,draw,thick}]


    \begin{scope}[xshift=15cm,scale=0.5,local bounding box=rightside box]
    \foreach \x in {0,1}
    {
        \foreach \y in {0,1,...,4}
        {
            \draw (\x*11,0) +(0,-\y*2) node[fullset,anchor=west] {};
            \draw (\x*11,0) +(\x*5+\y,-\y*2) node[oneblock,draw,anchor=west,fill=blue!50] {};
        }
    }
    \coordinate (R) at (rightside box.west);

    # Polygon

有些东西我刚刚复制过来我之前的回答，一个相对新颖的东西，以及一些我因为太标准（即无聊）而没有做的事情。复制的东西在图片的左下角，如果你自己收集这些东西，别人可能会更愿意帮助你，如果你只是尝试一下，你也会更喜欢它。相对新颖的东西是boards 矩阵。（它可以使用计数完全自动化，\pgfmatrixcurrentcolumn但更难理解/定制。）
