I'm trying to put the image onto a 132x233 table. The PNG image comes out to small and looks kinda jank when I try to use the table features to make it fit. Any advice on how I could get it the correct size for the table while still looking okay?

I don't know what "132x233 table" is. City maps are exported as 4000x4000 (approximately) bitmaps and that's as high resolution as I can manage without hacking too much. If it's not enough for you, you can try exporting them as SVG and rasterize the resulting vector images in Illustrator or something similar.
