I know that we can format different regressors (the rows of a estout table) of the same model using syntaxes like b(fmt(fmt1, fmt2...)), but how do you format regressors for differently columns (so a regression model) differently? So for example, esttab reg1 reg2 using myfile, how do I format all rows of reg1 differently from those of reg2? Or is estout not the best way of accomplishing this goal? Thanks in advance!
