latex width caption

It looks bad in my paper if a caption is wider than the table underneath it. How can I make them both align?

Right now my code looks like:

\begin{table}[th!]
\caption{Reference temperature blah blah}
\centering
\begin{tabular}{llll}
...
\end{tabular}
\end{table}

Answer

Actually there is a more legal way to do this using captions package option width.

For global effect

\usepackage[width=.75\textwidth]{caption}

For local effect only in current environment:

\usepackage{caption}
\captionsetup{width=.75\textwidth}
