# Table column justification when using the p attribute

I am using the p attribute so I can enable text wrapping. How can I get the second column, Numeric Rating to be center justified?

\documentclass{article}
\usepackage{multirow}
\usepackage[english]{babel}
\usepackage{booktabs}
\begin{document}
\begin{table}[H]
\centering
\begin{tabular}{ p{2.75cm} p{2.75cm} p{2.75cm} p{7cm} }
\toprule
Acceptability &Numeric Rating & General Rating & Improvement Implication\\ \hline
\multirow{3}{2.75cm}{Acceptable and Satisfactory} & 10 & Excellent & No obvious room for improvement \\
& 9 & Very Good & Minor improvement possible, but not required \\
& 8 & Good & Some improvement possible, but not required \\ \hline
\multirow{3}{2.75cm}{Acceptable but Unsatisfactory} & 7 & Fair & Limited Improvement requested \\
& 6 & Somewhat Poor & Significant improvement requested \\
& 5 & Poor & Major improvement requested \\ \hline
\multirow{4}{2.75cm}{Unacceptable} & 4 & Very Poor & Some improvement mandatory \\
& 3 & Bad & Significant improvement mandatory \\
& 2 & Very Bad & Major improvement mandatory \\
& 1 & Extremely Bad & Extensive improvement or major design changes are mandatory\\ \hline
& 0 & \multicolumn{2}{l}{Can't answer question, e.g., don't remember} \\
\bottomrule
\end{tabular}
\caption[General Rating Scale]{General Rating Scale}
\label{tab:genRating}
\end{table}
\end{document}

Nice that you post a minimal example! I would just like to note that it's not compilable, \usepackage{booktabs} is missing. –  Stefan Kottwitz Nov 19 '10 at 19:37
@Stefan, whoops forget to copy that over –  Elpezmuerto Nov 19 '10 at 19:39
thanks for correction! A good minimal example deserves a solution, so I checked it out. ;) –  Stefan Kottwitz Nov 19 '10 at 19:50

Load the array package, it provides a shortcut > for inserting commands into the column definition, this way you could insert \centering:
\usepackage{array}

\arraybackslash is a small helper macro which restores the meaning of \\ as \tabularnewline which might otherwise be destroyed by \centering.
