Taylor has stated on more than one occasion that tables will be made dynamic in the future
Actually, I went back through the code and it turns out that I already made this change last year. Apparently, even
I can't keep up with the things that I do.

So, the parser only has a limit of how much memory that you have available to actually parse the tbl. I think that there is another limit or two, but someone will actually have to try a super large tbl, figure out if it dies or doesn't parse correctly, and then let me know so that any remaining limits in that particular area can be fixed. Of course, you are far more likely to run into a ship or weapon limit before the tbl limit at the moment, until the new pilot file code gets here later this year at least.
