I am not able to center text in a multirow table, I want all column values to be centered here is the code
\begin{table}[]
\caption{$\alpha$ values obtained Analytically}
\label{table:Alphavalues}
\begin{tabular}{|l|l|l|l|}
\hline
OCL & Report (r) & Selection & Output \\ \hline
\multirow{2}{*}{99\%} & \multirow{2}{*}{20} & 20\% & 0.55 \\ \cline{3-4}
& & 40\% & 0.82 \\ \hline
\multirow{2}{*}{99\%} & \multirow{2}{*}{30} & 20\% & 0.77 \\ \cline{3-4}
& & 40\% & 0.76 \\ \hline
\end{tabular}
\end{table}
lstands for left-aligned columns. If you want centred columns then you should use thecspecifier. – campa May 07 '21 at 15:34ctype columns (instead ofl, like in your example) were used. – leandriis May 07 '21 at 17:06
