I have the following table
\begin{center}
\begin{tabular}{ |p{3cm}||p{3cm}|p{3cm}|
\hline
\multicolumn{3}{|c|}{Bosonic spectrum of type IIA and IIB theories} \\
\hline
Sector& IIA & IIB\\
\hline
NS-NS & graviton $g_{\mu \nu}$ & graviton $g_{\mu \nu}$ \\
NS-NS & dilaton $\phi$ & dilaton $\phi$\\ \hline
R-R & 1-form $C_1$& (axion)0-form $C_0$\\
R-R &3-form $C_3$ & 2-form $C_2$ \\
R-R & & (self-dual) 4-form $C_4$\\
\hline
\end{tabular}
\end{center}
which I do not know how to make it appear (how do I Latex in this forum?). I would like to do something so that the first column which has these NS-NS and R-R entries to be such that there is only one entry since the first three columns correspond all to NS-NS and the last three all correspond to R-$. That is I would like the first entry of the first column for the first three lines to be something like R{ (so the curly bracket to include all first three columns) and similarly for the last three ones.
How could I do this?
