Adjust table width to fit two-page column

Question

I want to fit my table into a two-column page and I am using a table* package. This is my code:

  \centering
  \begin{tabular}{@{}lllll@{}}
(table information)
\end{tabular}
  \label{tab:1}
\end{table*}

However, the sentence is too long, so the sentence exceeds the page margin. Would really appreciate if someone could help!
