I'm working on a mathematical problem (too much detail will be a spoiler) which involves getting data via a third-party program (there's a complicated algorithm involved that I do not understand, but the guy who wrote the program did).
The program produced data in the form of a LaTeX table (ampersand delimited) with, among other things, extremely many columns (it started at more than 30, and went up from there).
I have already searched on various ways of fitting the result into a page (landscape orientation, small font, shrinking the whole thing, etc). They worked well enough in the simple cases (up to around 150 columns).
However, I've encountered a bigger problem.
My latest table is about 300 columns wide (301 or 302, I think), but when I put it in my MiKTeX (and add the header, and shrink, and landscape-orient, etc) I can only see the data in the last several dozen columns. Most of the rest is empty.
The number of surviving columns is close to 300-256, so I suppose it could be a byte overflow. No idea what it is really.
As such: is there any reasonable way (package, environment, ...) to make the table work so that all the 300 columns are visible? (Assuming that if the text is there, however small, it counts as visible; since it's a vector format, I can always just crank up the PDF magnification.) If yes, would it mesh well with the usual shrinking methods (shrinking the table object, in particular)?
Bonus: is there a (reasonably easy) way to make the document sheet itself large enough to fit the table? I'd rather not need too much magnification, because on some models of PDF viewers, it only goes up so far (in some cases, IIRC, as low as 8x).
