我需要制作一些类似这里给出的图表。但是，我需要每个图表中都有大小相等的适当方块，而不管方块内有多少文本。请提供任何指导。
\documentclass[12pt]{article}
\usepackage[margin=1in]{geometry}
\usepackage{nccmath, amsmath}
\usepackage{lipsum}
\usepackage{array}
\begin{document}
\lipsum[1]
\newcommand\mc[1]{\multicolumn{1}{l}{#1}}
\centering
\begin{tabular}{|c|c|c|c|c|c|c|c|c|}
\mc{a} & \mc{b} & \mc{c} & \mc{d} & \mc{e} & \mc{f} & \mc{g} & \mc{h} & \mc{i} \\ \cline{1-9}
\it{S} & $C_1$ & $C_2$ & $C_3$ & $C_4$ & $C_5$ & $C_6$ & $C_7$ & $C_8$ \\ \cline{1-9}\end{tabular}
\lipsum[2]
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c}
\mc{a} & \mc{b} & \mc{c} & \mc{d} & \mc{e} & \mc{f} & \mc{g} & \mc{h} & \mc{i} & \mc{} \\ \cline{1-9}
\it{S} & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 36 \\ \cline{1-9}
1 & \it{S} & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 29 \\ \cline{1-9}
2 & 1 & \it{S} & 1 & 2 & 3 & 4 & 5 & 6 & 24 \\ \cline{1-9}
3 & 2 & 1 & \it{S} & 1 & 2 & 3 & 4 & 5 & 21 \\ \cline{1-9}
4 & 3 & 2 & 1 & \it{S} & 1 & 2 & 3 & 4 & 20 \\ \cline{1-9}
\end{tabular}
\lipsum[3]
\begin{tabular}{c|c|c|c|}
\mc{} & \mc{a} & \mc{b} & \mc{c} \\ \cline{2-4}
1 & \it{S} & 1 & 2 \\ \cline{2-4}
2 & \it{S} & 1 & $2\sqrt{2}$ \\ \cline{2-4}
3 & \it{S} & $2\sqrt{2}$ & 2 \\ \cline{2-4}
\end{tabular}

使用tabularray（正如@projetmbc 在其评论中所建议的）包：
\documentclass[12pt]{article}
\usepackage[margin=1in]{geometry}
\usepackage{tabularray}
\usepackage{lipsum}
\begin{document}
\lipsum[1]
\begin{center}
\begin{tblr}{hline{2,3}, vline{1-Z} ={2-Z}{solid},
colspec = {*{9}{Q[c, m, wd=2ex, mode=math]}},
row{2-Z} = {ht=4ex},
}
a & b & c & d & e & f & g & h & i \\
S & C_1 & C_2 & C_3 & C_4 & C_5 & C_6 & C_7 & C_8 \\
\end{tblr}
\end{center}
\lipsum[2]
\begin{center}
\begin{tblr}{hline{2-Z}={1-Y}{solid}, vline{1-Y}={2-Z}{solid},
colspec = {*{10}{Q[c, m, wd=4ex, mode=math]}},
colsep = 2pt,
row{2-Z} = {ht=4ex},
}
a & b & c & d & e & f & g & h & i & \\
S & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 36 \\
1 & S & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 29 \\
2 & 1 &S & 1 & 2 & 3 & 4 & 5 & 6 & 24 \\
3 & 2 & 1 & S & 1 & 2 & 3 & 4 & 5 & 21 \\
4 & 3 & 2 & 1 & S & 1 & 2 & 3 & 4 & 20 \\
\end{tblr}
\end{center}
\lipsum[3]
\begin{center}
\begin{tblr}{hline{2-Z}={2-Z}{solid}, vline{2-Z}={2-Z}{solid},
colspec = {*{9}{Q[c, m, wd=4ex, mode=math]}},
row{2-Z} = {ht=4ex},
}
& a & b & c \\
1 & S & 1 & 2 \\
2 & S & 1 & 2\sqrt{2} \\
3 & S & 2\sqrt{2} & 2 \\
\end{tblr}
\end{center}
\end{document}
