Maybe this is what you want? Please note that you have -estout- due to
Ben Jann (SSC).
sysuse auto, clear
global loopvars "price mpg weight length turn"
foreach x of varlist $loopvars {
	qui: estpost tab `x'
	mat define matpct = e(pct)
	mat define matcumpct = e(cumpct)
	mat A = (nullmat(A), (matpct[1,1..2] , matcumpct[1, 4])')
mat colnames A = "$loopvars"
matlist A

To every ω-consistent recursive class κ of formulae there correspond
recursive class signs r, such that neither v Gen r nor Neg(v Gen r)
belongs to Flg(κ) (where v is the free variable of r).
