# Maximizing page usage for a table

I'm printing a table enclosing 4 other data tables, one per page, and would like to maximize the space available by reducing the margins as much as possible. I still need the page number, but wonder if it can be made to take minimal space. My table contains resizebox'ed cells, so I wonder what surrounding mechanics can be employed to get rid of most of the margins specifically for those pages with such tables?

You can use the newgeometry macro from the geometry package to change the margins to suit.

\documentclass{article}
\usepackage[hmargin=3cm,showframe]{geometry}
\begin{document}
L1
\newgeometry{left=3cm,right=1cm,bottom=0.1cm}
\savegeometry{L2}
L2 (new, saved)
15
\restoregeometry
L1 (restored)
\newgeometry{margin=1cm,includefoot}
L3 (new)
