\begin{document}
All float placement specifiers are
shown together in the following table.
\begin{table}[H]
 \begin{tabular}{>{\ttfamily}cl}
  t & Top of page \\ b & Bottom of page\\
  p & Page of floats\\
  h & Here, if possible\\ H & Here, always
 \end{tabular}
 \caption{Specifiers}
\end{table}
With ``h'' instead of the ``H'' specifier
this text would have appeared before the
table in the current example.
