A Simple Table:

${\bf T}$	probability
2	$\frac{1}{36}$
3	$\frac{2}{36}$

                \begin{table}[h]
                \begin{center}
                \begin{tabular}{r|c}
                ${\bf T}$& {\bf probability}\\ \hline
                $2$ & $\frac{1}{36}$ \\
                $3$ & $\frac{2}{36}$ \\
                \end{tabular}
                \end{center}
                \end{table}

The vertical bars $\mid$ and $\backslash$hline commands control where horizontal and vertical lines appear in the table.
