Answer 1

您无需重新发明轮子，而是可以使用该romanbar包来书写带有上下横线的罗马数字：

\documentclass[12pt]{article}
\usepackage{romanbar}
\begin{document}
\begin{table}[h]
\centering
\begin{tabular}{|c|c|c|c|}
\hline
Standard & University & Board & Class\\
\hline
\Romanbar{12}\textsuperscript{th} & ABC & IIP & \Romanbar{2}\textsuperscript{nd}\\
\hline
\end{tabular}
\end{table}
\end{document}
