multirow and multicolumn without brackets (brackets doesn't change much in this case, but they should be there)

\begin{center}
\begin{tabular}{|c|c|c|}
\hline  & \multicolumn{2}{c}.\\
\hline A & B & C \\
\hline D & \multirow{2}{*}E & F \\
\hline & G &\\
\hline
\end{tabular}
\end{center}

... border added

\begin{center}
\begin{tabular}{|c|c|c|}
\hline  & \multicolumn{2}{c|}{.}\\
\hline A & B & C \\
\hline D & \multirow{2}{*}{E} & F \\
\hline & G &\\
\hline
\end{tabular}
\end{center}

multiple borders added (no effect if matching)

\begin{center}
\begin{tabular}{|c|c|c|}
\hline  & \multicolumn{2}{|c|}{.}\\
\hline A & B & C \\
\hline D & \multirow{2}{*}{E} & F \\
\hline & G &\\
\hline
\end{tabular}
\end{center}

\end{tabular}
\end{center}
