I have been trying to make this table
but I have a problem with the first row, the text "P kanal" and "Q kanal" aren't in the center here is what I get
The code I used:
\begin{tabular}{c c c c}
\hline
\hline
\rowcolor[RGB]{77,77,77}\color{white}\multirow{1}{}{Modulacijska} & \color{white}\multirow{1}{}{Biti na izlazu} & \color{white}\multirow{2}{}{\emph{I} kanal} & \color{white}\multirow{2}{}{\emph{Q} kanal} \\
\rowcolor[RGB]{77,77,77}\color {white} tehnika & \color{white} kanalnog prepletača & & \\
\hline
\hline
BSPK & $x_{0}$ & $x_{0}$ & - \\
\end{tabular}




\begin{document}
\begin{tabular}{cc} \rowcolor{gray} text & \multirow{2}{*}{covered text} \ \rowcolor{gray} text & \ \end{tabular}
\begin{tabular}{cc} \rowcolor{gray} text & \ \rowcolor{gray} text & \multirow{-2}{*}{correctly shown text} \ \end{tabular } \end{document}`help you?
