为 S Lloyd 的“从克朗代克回来”问题排版截断棋盘

Question

我正在尝试用 LaTeX 创建一个如下所示的表格：

从问题从克朗代克归来 我所能做的最好的就是

\documentclass[10pt]{article}
\begin{document}

\begin{table}[!h]
\begin{tabular}{*{21}{c}}
%\begin{tabular}{*{21}{c@{\hspace{1.25\tabcolsep}}}}
\cline{10-12}   & & & & & & & & &4&7&7& & & & & & & & &  \\
\cline{7-15}    & & & & & &5&4&4&8&3&3&4&6&3& & & & & &  \\

\cline{4-18}    & & &4&9&4&9&6&7&5&5&5&8&7&6&6&8&5& & &  \\
\cline{3-19}    & &3&7&2&9&8&3&5&6&7&3&9&1&8&7&5&8&5& &  \\
\cline{3-19}    & &1&4&7&8&4&2&9&2&7&1&1&8&2&2&7&6&3& &  \\

\cline{10-12}   & & & & & & & & & & & & & & & & & & & &   
\end{tabular}                       
\end{table}
\end{document}

它太丑了，我不会发布它：水平间距完全错误（而且我似乎无法使用来修复它1.25\tabcolsep）；没有垂直线；并且缺少棋盘背景。

理想情况下，我还可以添加从特定坐标到另一个坐标的箭头来指示解决方案。

任何帮助，将不胜感激！

matrix您可以使用包中的库来简单绘制截止检查板tikz：

\documentclass[margin=3mm]{standalone}
\usepackage{tikz}
\usetikzlibrary{matrix}


\begin{document}
    \begin{tikzpicture}

         nodes={draw, minimum size=1.5em,

                anchor=center},
         every even  column/.style={every odd row/.append style={nodes={fill=black, text=white}}},
         every odd  column/.style={every even row/.append style={nodes={fill=black, text=white}}},

@Zarko 的解决方案tikz可能是最好的。但仅供比较，该nicematrix包确实有命令，它可以通过使用和\chessboardcolors来创建类似的效果。请注意，您必须编译 3 次！cornershvlines

\documentclass{article}

\usepackage{nicematrix}
\begin{document}

\begingroup\renewcommand{\arraystretch}{1.4}
\begin{NiceTabular}{*{21}{c}}[corners, hvlines]
