What LaTeX is trying to do with this:
\documentclass{article}
\usepackage{floatflt}
\begin{document}
\begin{floatingtable}[r]{
\begin{tabular}{cc}
0 & 1 \\
1 & 0
\end{tabular}}
\end{floatingtable}
This is MWE.
\end{document}
I got
Underfull \hbox (badness 10000) in paragraph at lines 9--10
and message disappears if I add \raggedright
after \begin{document}
. It does not make any difference if I add more words to "This is MWE." -paragraph or add few paragraphs more.
\centering
just after the opening brace:\begin{floatingtable}[r]{\centering...
\centering
.Underfull \vbox
is exactly the one built by\floatingtable
.
