I have a big table generated from Stata software. I am trying to fit width of the table and have the table to stretch over multiple pages. I assume we can shrink the width a little bit to fit the width of the table in each page, but I was not sure how to have the table to be split over multiple pages.

tabularto longtable will probably be the most straight forward adjustment, although you will need to do more than that also depending on document class . Unrelated but STATA seems to have one of the worst converter to LaTeX--your table is going to need a lot of cleaning. Consider converting data toRand use export to LaTeX using kableExtra. – Celdor Mar 29 '23 at 07:28
