# Adding Tables to a Minipage Like Environment?

I'm trying to set up an environment to use for examples in my thesis document. I would like to increase margins, change the line spacing, open with "Example :", and close with $\Box$. Minipage works beautifully except I can't embed tables or figures within my examples.

This is what I have:

\newcounter{examplecounter}
\newenvironment{example}
{
\vspace{1.75em}
\begin{center}
\begin{minipage}[h]{0.85\textwidth}
\setlength{\parindent}{2em}
\refstepcounter{examplecounter}
\begin{oneandahalfspaced}
\noindent
\textbf{Example \arabic{examplecounter}:}
}{
\hspace{-1em}
$\Box$
\end{oneandahalfspaced}
\end{minipage}
\end{center}
\vspace{1.75em}
}

Any suggestions on how to accomplish what I'm looking for?

I tip about including other environments in \newenvironment s: Instead of e.g. \begin{center} ... \end{center} you can write \center ... \endcenter. This has the advantage that if the \end{example} is misplaced you get a proper warning, otherwise the name of most inner environment started with \begin{ will be printed, here: ! LaTeX Error: \begin{oneandahalfspaced} on input line XX ended by ... and people get confused because the never typed that environment by themselves. –  Martin Scharrer Feb 8 '11 at 10:02
Thanks for the tip Martin! –  Jason George Feb 8 '11 at 10:09

You cannot have a figure environment inside a minipage because its a float, same counts for table. However you can include an image using \includegraphics (graphicx package) and also add a caption using the capt-of package: \captionof{figuree}{<the caption text>}.
