Mixing a4 and a3 in one Latex file

I am finishing my thesis and have a large appendix. Some tables only look good, if first done on a3 and then (paper)printed on a4. Anyhow, working all the files seperalty is fine, but开发者_如何学JAVA I struggle to compile all in one.

I use the geometry package and start the document with:

\usepackage[a4paper,left=30mm,right=20mm,top=20mm, bottom=20mm]{geometry}

For the appendix, I want to include the table and use

\newgeometry{a3paper,left=25mm,right=15mm, top=15mm, bottom=15mm}

However, the command is completely ignored and I can read "a3paper,left=25mm,right=15mm, top=15mm, bottom=15mm" above the table.

What did I miss? Is it even possible? If not, how do I get the numbers right, if I have to include it as a pdf (which works)?

Thanks!

I don't think it's possible (at least if your output is DVI). Have a look at Change paper size in the middle of a latex document?.
