I have written the following code:

```
\begin{table}
%\centering
\caption{Performance of Mesh Topology.}
\label{tab:meshperformance}
  \begin{tabular}{|l|l|l|l|l|l|l||l||l|}
    \hline
    \multirow{2}{*}{Mesh Topology} &
      \multicolumn{2}{c|}{TH(Kbps)} &
      \multicolumn{2}{c|}{Energy(J)} &
      \multicolumn{2}{c|}{Delay(ms)} &
      \multicolumn{2}{c|}{PDR (\%)} \\ \midrule 

    & MD/MA,  & MD/MA,  & MD/MA,  & MD/MA, & MD/MA,  & MD/MA,  & MD/MA,  & MD/MA,  \\
    &T=1   & T=5   & T=1   & T=5   & T=1   & T=5   &T=1   &T=5 \\ \midrule 
    With Fusion & 2.1\% & 2.1\% & 2.1\% & 2.1\% & 2.1\% & 2.1\% & 2.1\% & 2.1\% \\
    \hline
    Without Fusion & 11.6\% & 11.6\% & 11.6\% & 11.6\% & 11.6\% & 11.6\% & 2.1\% & 2.1\% \\
    \hline
    %D3 & 5.5\% & 5.5\% & 5.5\% & 5.5\% & 5.5\% & 5.5\% & 2.1\% & 2.1\%  \\
    \hline
  \end{tabular}
\end{table}

```

this is what i am getting the output as:[![enter image description here](https://i.stack.imgur.com/M79He.png)](https://i.stack.imgur.com/M79He.png)
