[Tex/LaTex] Line break in rotatebox in table

Question

I use \rotatebox to create a table with vertical headers, like so:

\documentclass{article}

\usepackage{rotating}

\begin{document} 

\begin{table}
\begin{tabular}{|l|l|l|}
\hline
\rotatebox{90}{Header 1} &
\rotatebox{90}{Header 2} &
\rotatebox{90}{Header 3}\\
\hline
Content & Content & Content\\
\hline
\end{tabular}
\end{table}

\end{document}

Now, I have a header that is awkwardly long (and cannot be abbreviated in a meaningful way). I would like to break the header into two lines. However, I can't seem to get this to work with \linebreak or \\, so apparently some trickery is needed.

Help?

Answer 1

How about putting the "problematic" header into a \parbox and manually adding \\ (which works inside the box) where necessary?

\documentclass{article}

\usepackage{rotating}

\begin{document} 

\begin{table}
\begin{tabular}{|l|l|l|}
\hline
\rotatebox{90}{Header 1} &
\rotatebox{90}{Header 2} &
\rotatebox{90}{\parbox{4cm}{An awkwardly long \\header that cannot be \\abbreviated in a \\meaningful way}}\\
\hline
Content & Content & Content\\
\hline
\end{tabular}
\end{table}

\end{document}
