Fitting Regression Table into LaTeX

I’m trying to fit tables to page-width that I include in the .tex document. I’m doing this because I’m exporting tables from Stata to Latex with the estout methods, and include these tables into my document. However, some tables are too wide and I’d like to scale them down to make them fit.
