Wrapping text in Sidewaystables

Question

I'm trying to make a rotated table using the sidewaystable package, and I cannot get the text to wrap. It compiles, but it I haven't been able to wrap the text within the columns or define the width of the columns.

The code is rather messy but here is an extract:

\begin{sidewaystable}[htbp]  
  \centering  
  \caption{bla bla bla}  
   \begin{threeparttable}[b]  
    \begin{tabular}{rrr}  
    \toprule  
          Awesome intro\\  
    \midrule  
    \multicolumn{1}{l}{bla bla} & \multicolumn{1}{l}{more bla} & \multicolumn{1}{l}{final bla} \\  
\bottomrule  
    \end{tabular}%  
    \begin{tablenotes}\footnotesize  
        \item Source: bla bla  
         \end{tablenotes}  
    \end{threeparttable}  
  \label{tab:xx}%  
\end{sidewaystable}%  

Edit:

• It is also going on a seperate page in the appendix, if that makes a difference..
• I am using the threeparttable to be add "footnotes" to the tables.

Use p{...} type columns and avoid the \multicolumn{1}{l}{...} which override the initial column type; you can still use \multicolumn with a p{...} column type to merge several columns. A little example:

\documentclass{article}
\usepackage{booktabs}
\usepackage{array}
\usepackage{rotating}
\usepackage{threeparttable}

\begin{document}

\begin{sidewaystable}[htbp]  
  \centering  
  \caption{bla bla bla}  
   \begin{threeparttable}[b]  
    \begin{tabular}{p{4cm}p{4cm}p{4cm}}  
    \toprule  
          Awesome intro\\  
    \midrule  
    Some test text spanning several lines & Some test text spanning several lines  & Some test text spanning several lines  \\ 
   \multicolumn{2}{>{\centering}p{8cm}}{Some test text spanning several lines in a multicolumn for two columns} & Some test text spanning several lines \\
\bottomrule  
    \end{tabular}%  
    \begin{tablenotes}\footnotesize  
        \item Source: bla bla  
         \end{tablenotes}  
    \end{threeparttable}  
  \label{tab:xx}
\end{sidewaystable}

\end{document}
