I would like the sentence "Why get someone who only pretends to be a doctor when you could get a real one?" to fit into this 430pt table. But the sentence doesn't break after "could" and keeps running out of line. Shouldn't long sentences automatically break into paragraph in tabularx? How can I fix it?

\documentclass[11pt]{book}
\usepackage{tabularx,pbox}
\begin{document}
\begin{table}
\begin{tabularx}{430pt}{|c|X|}
\hline
\textbf{Paragraph \#} & \textbf{Description:} \\
\hline
1 & \pbox{20cm}{\emph{Rhetorical questions/Introduction} \\
Why get someone who only \emph{pretends} to be a doctor when you
could get a real one? \\ \emph{Relate to audience} \\ Some more sentence
here.} \\
\end{tabularx}
\end{table}
\end{document}
I could insert \\ after "could" to manually break the line. But that would totally defeat the purpose.


\tabularnewlinemean to introduce new row? I think it's clearer than\\. Your table looks pretty btw. But I'm wondering how come the vertical rules don't connect at the corners? – pineapple Jun 02 '14 at 09:02\topruleand friends, you mustn't use vertical rules. That's the principlebooktabsis based on. – egreg Jun 02 '14 at 09:08
