I have written code for a three column table, but it extends beyond the column margin. How can I fit it in the double column setting of my document.
\begin{table}
\centering
\begin{tabular}{|c|c|c| }
\hline
\textbf{Original Pair }&\textbf{ Mapped Pair}&
\textbf{Favourable/Alternative}\\
\hline
a,a & e,g & Favourable \\
\hline
b,b & e,c & Favourable\\
\hline
c,c & g,e & Favourable \\
\hline
d,d & h,f & Favourable\\
\hline
a,c & a,c & Favourable\\
\hline
c,a & c,a & Favourable\\
\hline
b,d & b,d & Favourable \\
\hline
d,b & d,b & Favourable \\
\hline
a,b & e,c & Alternative\\
\hline
a,d & a,g & Alternative \\
\hline
b,a & e,g & Alternative \\
\hline
b,c & a,c & Alternative\\
\hline
c,b & g,a & Alternative \\
\hline
c,d & c,e & Alternative \\
\hline
d,a & d,f & Alternative \\
\hline
d,c & h,b & Alternative \\
\hline
\end{tabular}
\end{table}
