 \hline
 Dataset & Samples \\ [0.5ex] 
 \hline\hline

 \hline

 \hline


\end{tabular}
\end{center}
Solution

  • My minimal code:

    \documentclass{article}

\setlength{\tabcolsep}{1em}
\renewcommand{\arraystretch}{1.5}

\begin{document}

\begin{table}[htbp]
  \centering
  \begin{tabular}{|c|c|}
    \hline
    Dataset & Samples \\
    \hline
    Covid & 349 \\ 
    Non Covid & 397 \\
    \hline
  \end{tabular}
  \caption{Dataset Specifications}
  \label{tab:data}
\end{table}

\end{document}
