Do you know how can I merge 4 cells from two different collums and two rows? Can I use both multicol and multi row? Thanks
\multicolumn{2}{|c|}{Population to serve}\multirow{2}{6cm}{Population to serve} Something like this?
\documentclass{article} \usepackage{array,multirow} \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|}{} \\ \hline \end{tabular} \end{document} \multirow needn't be an integer. Since I've also set \setlength\extrarowheight{2pt}, it seemed appropriate to use 2.2 instead of just 2. With package 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}
tabularraypackage. It make merging cells very easy.
