This is an example of TABLE.  
\LaTeX can make fancy tables easily.  

\begin{table}
        \begin{tabular}{|r|r|r|} \hline
        animal   & weight & comments \\ \hline
        cat      & 1      & light    \\ \hline
        tiger    & 100    &          \\ \hline
        elephant & 1000   & heavy    \\ \hline
        \end{tabular}
    \caption{This is a table created by \LaTeX.}
    \label{ABC}
\end{table}

The table can be referred as Table \ref{ABC}.
