Creating a resume template - need help with the education part

Question

I am working on creating a resume template for people like me aka complete newbies to Latex, exploring the lay of the land. I have been working on modularizing what I have and while working on the education part, I started with creating a table of two columns, the contents of which are flushed left, and ragged right (to push the dates to the extreme right). Here's the code for my education section:

\vspace{-4mm}
\begin{table}[htbp]
  \centering
  \begin{tabularx}{\textwidth}{p{0.75\textwidth}>{\raggedleft\arraybackslash}p{0.25\textwidth}}
     \textbf{Ms. in Computer Science}, Northeastern University, MA & Sept. 2021 - May 2023 \\
     \textbf{B.E in Computer Engineering}, Pune University, IN & Aug. 2016 - May 2020
  \end{tabularx}
\end{table}
\vspace{-7mm}

And I am trying to create a style file .sty for storing the commands, importing appropriate libraries. Please help me create three new commands from the above code:

1. ResumeEducationListStart - to include

\vspace{-4mm}
\begin{table}[htbp]
  \centering
  \begin{tabularx}{\textwidth}{p{0.75\textwidth}>{\raggedleft\arraybackslash}p{0.25\textwidth}}

2. ResumeEducationItem - to include

\textbf{Ms. in Computer Science}, Northeastern University, MA & Sept. 2021 - May 2023 \\

and finally 3. ResumeEducationListEnd - to include

\end{tabularx}
\end{table}
\vspace{-7mm}

For some reason, I can not simply break the code into three: The error hints at the 'table' being started and ending at \end{document}
