I am trying to create a \multirow and \multicolumn table in Texmaker. I have specified to put vertical lines in the code but somehow my last column is missing partially the vertical line. I have posted my code below. Could someone help me out to understand where am I wrong? Thanks a lot in advance.
\begin{table}[h]
\centering
\begin{tabular}{|p{3cm}|p{3cm}|p{3cm}|} \hline
Macrophase & \multicolumn{2}{|c|}{Activity} \\ \hline
\multirow{8}{*}{} & Description & \\ \cline{2-3}
& Macrophase Actors \\ \cline{2-3}
& Duration and Frequency \\ \cline{2-3}
& Inputs \\ \cline{2-3}
& Software Utilized \\ \cline{2-3}
& Outputs \\ \cline{2-3}
& Criticalities \\ \cline{2-3}
& KPIs \\ \hline
\end{tabular}
\caption{caption}
\label{table:sample}
\end{table}
