multirow with color does not work properly

Question

First, there is not any error message, but I have this problem in which I want to merge rows horizontally, but I do not know why the text appears like that:

Code:

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{graphicx,color}
\usepackage{array}
\usepackage{multirow}
\begin{document}
\begin{table}
\centering
\arrayrulecolor{gray}
\caption{Statistics}\label{tab8}
\rowcolors{2}{gray!50}{white!10}
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|} 
\hline

 \multirow{2}{}{\textbf{country}} &
\multirow{2}{}{\textbf{GDP}} &
\multicolumn{2}{|c|}{\textbf{Sex}} \
& & \textbf{male} & \textbf{female} \
 A&B&C&D\ 
 A&B&C&D\ 
 A&B&C&D\ 
 \end{tabular}
 \end{table}
\end{document}

I want the merged cells to be colored with only one color.

Thank you for your help.

You should provide a complete MWE (minimal working example) with the \document{classe}, \usepackage{...}, etc. — F. Pantigny, Mar 09 '22 at 10:08

The environment {NiceTabular} of nicematrix has a command \rowcolors able to color rows with alternance while respecting the blocks (with the key respect-blocks).

\documentclass{article}
\usepackage{graphicx,color}
\usepackage{nicematrix}
\usepackage{caption}
\begin{document}
\begin{table}
\centering
\arrayrulecolor{gray}
\caption{Statistics}
\begin{NiceTabular}{|cccc|} 
\CodeBefore
  \rowcolors{1}{gray!50}{white!10}[respect-blocks]
\Body
  \Hline
  \RowStyle[bold,nb-rows=2]{}
  \Block{2-1}{country} &
  \Block{2-1}{GDP} & \Block{1-2}{Sex} \
  & & male & female \
  A&B&C&D\ 
  A&B&C&D\ 
  A&B&C&D\ 
  \Hline
\end{NiceTabular}
\end{table}
\end{document}

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood).

By using \multirow{-2}{*}{text} you can properly colorize the background of the two rows.

MWE:

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{array}
\usepackage{multirow}
\begin{document}
\begin{table}
\centering
\arrayrulecolor{gray}
\caption{Statistics}\label{tab8}
\rowcolors{3}{white}{gray!20}
\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|}
\hline
\rowcolor{gray!35}
& & \multicolumn{2}{c|}{\textbf{Sex}}\
\rowcolor{gray!35}
\multirow{-2}{}{\textbf{country}} &
\multirow{-2}{}{\textbf{GDP}} &
\textbf{male} & \textbf{female}\
\hline
Row 1 & & &\
Row 2 & & &\
Row 3 & & &\
Row 4 & & &\
\hline
\end{tabular}
\end{table}
\end{document}

Thank you for your help but there is no line under Sex column, how can I show it up? – Hamzah Mar 09 '22 at 10:30
I don't know a way to do it, but I'd advise you to not do it. These are the reasons: problem with cline in multirow, colored tabular and How does \hhline work? – Rui Antunes Mar 09 '22 at 10:48
