[Tex/LaTex] Break url in tabular

line-breakingtablesurls

How can I break hyperref URLs in a tabular environment. Consider the following example:

\documentclass{article}

\usepackage[colorlinks=true,linkcolor=black,anchorcolor=black,citecolor=black,menucolor=black,runcolor=black,urlcolor=black,bookmarks=true]{hyperref}
\usepackage{breakurl}

\begin{document}

\url{http://www.avery/long/url?zz/very/very/long/this/should/break/very/long/long.html}

\begin{tabular}{l l}
   A long url &
\url{http://www.avery/long/url?zz/very/very/long/this/should/break/very/long/long.html}

\end{tabular}


\end{document}

The first one breaks, the second one doesn't. The output looks like:

url

I am using pdflatex.

Use the p{10.0cm} column specification, which require a length. This makes the column able to have line breaks:

\documentclass{article}

\usepackage[colorlinks=true,linkcolor=black,anchorcolor=black,citecolor=black,menucolor=black,runcolor=black,urlcolor=black,bookmarks=true]{hyperref}
\usepackage{breakurl}

\begin{document}
\noindent
\url{http://www.avery/long/url?zz/very/very/long/this/should/break/very/long/long.html}

\noindent
\begin{tabular}{l p{10.0cm}}
   A long url &
\url{http://www.avery/long/url?zz/very/very/long/this/should/break/very/long/long.html}
\end{tabular}
\end{document}

You can reset the width on the border. The needed value depends on the resolution settings of dvips. E.g. with dvips -Ppdf a value of 100 is okay, without -Ppdf you can try 5.

\documentclass[a4paper,10pt]{article}

\usepackage{hyperref}
\usepackage{breakurl}
\hypersetup{pdfborder={0 0 100}}
\textwidth=3cm
\begin{document}
\url{long/long/long/long/long/long/blub/bla/bla}
\end{document}

[Tex/LaTex] Manually breaking a long URL (in the bibliography)

Update: This question's OP himself has found a good solution between an extra \\ and a working hyperref.

With the help of the hyperref package one can write (the example is changed to an unpublished publication because there is, apparently, no journal):

@unpublished{koepke2009naturalness,
  year={2009},
  title={Naturalness in formal mathematics},
  note={\\
        \href{http://www.math.uni-bonn.de/people/koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             {\nolinkurl{http://www.math.uni-bonn.de/people/}}
        \\
        \href{http://www.math.uni-bonn.de/people/koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             {\nolinkurl{koepke/Preprints/Naturalness_in_formal_mathematics.pdf}}
       },
  author={Koepke, Peter}
}

which gives
$Output with two \hrefs$

If only one \href is used, like

  note={\\
        \href{http://www.math.uni-bonn.de/people/koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             {\nolinkurl{http://www.math.uni-bonn.de/people/}
             \\
              \nolinkurl{koepke/Preprints/Naturalness_in_formal_mathematics.pdf}
             }
       },

the link-active area spans the whole first line: $Output with one \href$

Original answer

An underfull hbox doesn't mean that there's necessarily something wrong. It is merely a warning.

Compare the bibliography entries of the following code.
The one with the extra \\ doesn't give a warning (but breaks the hyperlink, by the way), the other one does give a warning, but looks the same.

(The italic setting from the journal field did mess up the spacing either way.)
