Make LaTeX table caption same width as table?

Question

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 1

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}

More info in caption package doc:

Answer 2

if you know or find out the width of the table, let's say 5cm -

• if you're using a KOMA-Script class:

  \\setcapwidth[c]{5cm}

• if you're using the caption package:

  \\captionsetup{width=5cm}

Both may be applied inside the table environment.

An automatically calculating solution is more complicated, but could be done using the \\settowidth command.

Answer 3

通过将我的标题放在parbox中我获得了成功：

\parbox{5cm}{\caption{Lorem ipsum dolor sit amet...}}

Answer 4

in caption package guide:

Only fixed widths are supported here; if you are looking for a way to limit the width of the caption to the width of the figure or table, please take a look at the floatrow [8] or threeparttable [22] package.

Answer 5

Put your table plus caption inside a minipage. The caption will wrap. This is also a great way to have proper footnotes for tables.
