\setlength\extrarowheight{2pt} % optional
\begin{document}

\begin{tabular}{|c|c|c|}
\hline
a & b & c \\
\hline
d & \multicolumn{2}{c|}{\multirow{2.2}{*}{efhi}}  \\
\cline{1-1}
g & \multicolumn{2}{c|}{}  \\

带包装NiceMatrix / NiceTabular

\documentclass{article}
\usepackage{nicematrix,booktabs}

\begin{document}
    
    \begin{table}
        \begin{NiceTabular}[]{cccc}  
            \CodeBefore
            \rectanglecolor{blue!20}{2-1}{3-2}
            \Body
            \toprule  
            Column1&Column2&Column3&Column4\\ \midrule
            \Block{2-2}{R2*C2}& &Row2  &Row2   \\ 
                                        &&Row3&Row3\\
            \bottomrule
        \end{NiceTabular} 
    \end{table}
    
\end{document}
