example of wrapping text within tables in LaTeX. Created for the wikibook. I created it with the following code:

\documentclass{article} 

\usepackage[english]{babel}

\begin{document}

Without specifying width for last column:

\begin{center}
        \begin{tabular}{ | l | l | l | l |}
        \hline
        Day & Min Temp & Max Temp & Summary \\ \hline
        Monday & 11C & 22C & A clear day with lots of sunshine.  However, the strong breeze will bring down the temperatures. \\ \hline
        Tuesday & 9C & 19C & Cloudy with rain, across many northern regions. Clear spells across most of Scotland and Northern Ireland, but rain reaching the far northwest. \\ \hline
        Wednesday & 10C & 21C & Rain will still linger for the morning. Conditions will improve by early afternoon and continue throughout the evening. \\
        \hline
        \end{tabular}
\end{center}

With width specified:

\begin{center}
        \begin{tabular}{ | l | l | l | p{5cm} |}
        \hline
        Day & Min Temp & Max Temp & Summary \\ \hline
        Monday & 11C & 22C & A clear day with lots of sunshine.  However, the strong breeze will bring down the temperatures. \\ \hline
        Tuesday & 9C & 19C & Cloudy with rain, across many northern regions. Clear spells across most of Scotland and Northern Ireland, but rain reaching the far northwest. \\ \hline
        Wednesday & 10C & 21C & Rain will still linger for the morning. Conditions will improve by early afternoon and continue throughout the evening. \\
        \hline
        \end{tabular}
\end{center}

\end{document}
