I want a Table that looks like this, 
The code that I use in Overleaf is this below,
\documentclass{article}
\begin{document}
\begin{table}[h!]
\centering
\begin{tabular}{|c|c|c|c|c|}
\hline
\textbf{Metrices} & \textbf{UTL} & \textbf{BEC} & \textbf{CTH} & \textbf{IWW} \\
\hline
\textbf{Ge Fraction (in D4R)} & 12 & 24 & 16 & 4 \\
\hline
\textbf{Total CN (Ge-Ge)} & 28 & 20 & 9 & 7 \\
\hline
\hspace{0.6cm} \newline \textbf{D4R,} & 12, & 24, & 16, & 4, \\
\textbf{Occu Freq} \newline \textbf{Adj,} & 15, & 43, & 5, & 10, \\ \hspace{0.6cm}
\newline \textbf{ Frw} & 20 & 20 & 8 & 7 \\
\hline
\end{tabular}
\end{table}
\end{document}
The result of this looks like this, 
Please suggest how to align the D4R, Adj, and Frw in the same way as intended. Thanks.
