How to set a default border for each cell in table?

Question

I have a document which has some tables in it and I want to set some default border for each cell in the table. Right now I have defined a new command and I have to call that command for each cell but I don't want to do this. I want to set it as default so that every cell will have the same border. Is there a command which can solve my problem. My current code is like this

\documentclass[11pt]{article}
\usepackage{blindtext}
\usepackage{xcolor}
\begin{document}
\newcommand{\comm}[1]{
    \setlength{\fboxrule}{2pt}
    \fcolorbox{red}{white}{#1} 
}
\begin{center}
\begin{tabular}{ c c c }
     \comm{cell1} & \comm{cell2} & \comm{cell3} \\  
\end{tabular}
\end{center}
\end{document}

Here I don't want to call commad "comm" for each cell.

If you want to wrap a macro around each cell, you may be interested in collcell.

\documentclass[11pt]{article}
\usepackage{xcolor}
\usepackage{array}
\usepackage{collcell}
\usepackage{colortbl} % < for alternative
\begin{document}
\newcommand{\comm}[1]{
    \setlength{\fboxrule}{2pt}
    \fcolorbox{red}{white}{#1} 
}
\newcolumntype{E}{>{\collectcell\comm}c<{\endcollectcell}}
This wraps the content of each cell in your macro:
\begin{center}
\begin{tabular}{*3{E}}
     cell1 & cell2 & cell3 \\  
\end{tabular}
\end{center}
Are you sure you do not want:
\begin{center}
\setlength\arrayrulewidth{2pt}%
\arrayrulecolor{red}%
\begin{tabular}{|*3{c|}}
    \hline
     cell1 & cell2 & cell3 \\  
     \hline
\end{tabular}
\end{center}
\end{document}
