Although I have a valid label for a table, the reference to that label does not appear in the PDF file, or sometimes appear as ?? if I put a tilde before \ref.
The code is the following:
\documentclass{article}
\begin{document}
\begin{table}[!t]
\footnotesize
\parbox{.50\linewidth}{
\centering
\begin{tabular}{l|l}
Example plot \\ \hline
A & 22 \% \\
B & 54 \% \\
\end{tabular}
}
\label{tab:example}
\caption{Example plot}
\end{table}
Looking the table \ref{tab:example}
\end{document}
Any thought?
