When there are many short footnotes on one page, it looks bad to use a whole line for each. Classical typography solves this problem by arranging consecutive short footnotes in columns (the number of columns varying according to the number and order of short footnotes on each page). How would one do this in LaTeX?
\documentclass{article}
\usepackage{showframe}
\begin{document}
\begin{tabular}{lll}
$^1$\,First footnote.\kern .75in & $^2$\,Second.\kern .75in & $^3$\,Third.\kern .75in\\
$^4$\,Fourth.\kern .75in & $^5$\,Fifth.\kern .75in & $^6$\,Sixth.\kern .75in
\end{tabular}
\end{document}
(I used \kern because I don’t know how to distribute columns horizontally evenly; but of course that is what should be done.)
When there is one or more footnotes on a page, that are considerably shorter than one line but longer than half a line, they should be centered and aligned.





\footnoteAand\footnoteB, which both use the same counter for numbering the footnotes. – Keks Dose Sep 09 '15 at 19:39
