请告诉我如何使此表中的值显示在中心.

\begin{table}[h]
    \begin{center}
\caption{Mobile IP throughput statistics}
        \begin{tabular}{ | p{2.5cm} | p{2.5cm} | p{2.5cm} | }
            \hline Speed (km/hr) & Max (packets/sec)  & Sample mean (packets/sec) \\
            \hline 20 & 261.67 &  209.05\\
                           \hline 70 & 262.5 &  207.91\\
                           \hline 80 & 259.58 &  209.03\\ 
                           \hline 90 & 260.75 &  209.47\\
                           \hline 100 & 260.33 &  209.3\\
                            \hline 120 & 262.42 &  210.4\\
                            \hline 160 & 259.08 &  210.29\\                                 
            \hline
        \end{tabular}

        \label{table:table3}
    \end{center}
\end{table}
