答案1
您的代码有很多错误，下面是更正后的代码：
\begin{tabular}{|cc|cc|cc|cc|c}
\cline{1-8}
\mc{|c|}{3} && && && & & 3 \\[6pt]\cline{1-1}
& \mc{c|}{2} && \mc{c|}{2} && \mc{c|}{2} &&
\mc{c|}{1} & \\ \cline{1-8}
\mc{|c|}{1} && \mc{c|}{3} && \mc{c|}{3} && & & 7 \\[6pt]\cline{1-1}\cline{3-3}\cline{5-5}
& \mc{c|}{10} && \mc{c|}{8} && \mc{c|}{5} && \mc{c|}{4} & \\ \cline{1-8}
&& && \mc{c|}{1} && \mc{c|}{4} & & 5 \\[6pt]\cline{5-5}\cline{7-7}
& \mc{c|}{7} && \mc{c|}{6} && \mc{c|}{6} && \mc{c|}{8} & \\ \cline{1-8}
\Mc[2]{c}{4} & \Mc[2]{c}{3} & \Mc[2]{c}{4} & \Mc[2]{c}{4} & \\
