I created a table using this code:


\begin{document}
\begin{table*}
\centering\ra{1.3}
\begin{tabular}{@{}rcccccc@{}}
\toprule &  \textit{Accuracy} & \phantom{abc}& \multicolumn{3}{c}{\textit{Time}} \\
\cmidrule{4-6} &&& $t=0$ & $t=1$ & $t=2$
\\ \midrule
$c$ & 9 && 1 & 1 & 3\\
$c$ & 9 && 1 & 1 & 3\\
$c$ & 9 && 1 & 1 & 3\\
\bottomrule
\end{tabular}
\caption{Caption}
\end{table*}


How can I align the heading "Accuracy" to middle of the row (the red text in the picture)?


One way is to use the multirow package and replace \textit{Accuracy} by \multirow{2}{*}[-3pt]{Accuracy} (args are: number of rows, width (* for natural width), fine tuning vertical position (optional), text).
