I have a table that is very wide. Now I want to force it into one landscape page. I already set the page orientation to landscape but now I don't know how to force it into one page with scaling. Any hints?

You can use the adjustbox package with:

begin{adjustbox}{width=textwidth,totalheight=textheight,keepaspectratio}

   % your table

end{adjustbox}

You can also use the graphicx package with:

setkeys{Gin}{keepaspectratio}

resizebox*{textwidth}{textheight}{your table}

but adjustbox is more recommended. It doesn't read the whole table as an argument.

You can also add rotatebox{90}{..} or the angle=90 option to the adjustbox environment to implement the rotation.

You might need to exchange textwidth and textheight because of the landscape mode. Also you should use an approximate font size first, e.g. try tiny or scriptsize and let the rest be done by scaling. You shouldn't scale the normal font size to a very small size. Many fonts are differently designed in different sizes, so using the closest possible size yields the best results.

I assume you want to scale down just the contents of the tabular environment, while leaving the fontsize of the caption unchanged. If you use the rotating package, you can avail yourself of its sidewaystable environment, which automatically rotates its contents by 90 degrees. (Internally, the package relies on the graphics/x package.) With this environment, you needn't keep track of whether textheight and textwidth need to be interchanged or not.

begin{sideswaystable}

caption{A very wide table}label{tab:verywide}

centering

scriptsize %% or tiny -- see remark below

begin{tabul...

...

end{tabul...

end{sidewaystable}

Remark: If the tabular material has so many columns that it won't fit on a rotated page even if the fontsize has been set to either scriptsize or tiny, you may want to consider seriously breaking up the table into two subtables and displaying them separately. Realistically, very few readers are going to bother reading something in a font size smaller than 5 or 6pt. Hence, if you have to use both the tiny fontsize instruction as well as the adjustbox command with a shrinkage factor of well below 1, chances that anyone is going to read your carefully designed tabular material are, well, smaller than tiny.
