I'm trying to create a table in LaTeX where I want all cells to have a red background color. Here's an example of the table structure:
\begin{tabular}{|l|l|l|}
\hline
\multirow{3}{*}{\textbf{RM - Realización de la memoria}} & \textbf{Primer prototipo 01/12/2022} & \\
& \textbf{Segundo prototipo 04/02/2023} & \textbf{X} \\
& \textbf{Entrega Final 15/03/2023} & \\
\hline
\end{tabular}
I've tried using \cellcolor{red} and \columncolor{red} but only managed to color individual cells or half of the column. How can I set the entire column to have a red background color?
I would appreciate any insights or suggestions on how to achieve this. Thank you in advance for your help.
