Generate a grading table for exam using tabularray

Question

I would like to have two commands that automate the generation of both vertical and horizontal grading tables to look the same as those manually written by me below.

\documentclass[a4paper,addpoints,11pt]{exam} 

\marksnotpoints

\usepackage{tabularray}
\UseTblrLibrary{booktabs, siunitx}

Answer 1

Why not use the built-in \gradetable command from the exam class.

\documentclass[a4paper,addpoints,11pt]{exam} 
\marksnotpoints
\vpword{Marks}
\hpword{Marks:}%<--
\begin{document}
\begin{coverpages}

\begin{center}
\gradetable[h][questions]%<--
\end{center}

\begin{center}
\gradetable[v][questions]%<--
\end{center}

\end{coverpages}
\begin{questions}
        \question[10]
        Example question
        \question[20]
        Example question
        \question[30]
        Example question
\end{questions}  
\end{document}
