Tables below footnotes, is this a good output routine algorithm or a bug?
Whenever a page contains a figure which is set to be placed at the bottom of the page, and the page also contains a footnote, the figure ends up below the footnote. I don't like this appearance; it looks odd and gives a feel that the figure belongs to the footnote instead of the main text.
How do I fix so that the footnote stays at the bottom of the page, and the figure is placed on top of it, even when its positioning marker is set to b? Here is a minimal example:
\documentclass[a4paper, 11pt]{article}
\usepackage{tikz}
\usepackage{lipsum}
\begin{document}
\begin{figure}[b]
\begin{tikzpicture}
\node [%
draw,
rectangle,
fill=black,
minimum size=5mm,
] {};
\end{tikzpicture}
\end{figure}
\lipsum[5] more\footnote{Bla bla bla bla bla}
\end{document}

(Yes, my drawing skills are awesome.) =)
\usepackage[bottom]{footmisc}is what you are looking for. But probably it's best to avoid bottom floats where footnotes are used. – egreg Jan 05 '12 at 10:04
