If you want a non-standard table than you have to use more general
techniques. The difficulty with that is that the extra flexibility
comes with extra work on your side.

-tabdisp- is a way of displaying the literal content of a dataset as
if it were a table, that is, the contents of the cells is already in
the dataset. You can create such datasets using -collapse- and/or
-contract-. You typically do not want to save such datasets, so you
would do well to precede the whole operation with -preserve- and end
it with -restore-. Anyhow, I would just start simple with only the
means or the frequencies, and after you got that working add the other
statistic. Below is an example to get you started

*---------------- begin example -------------------
sysuse auto, clear

preserve
collapse (mean) mpg, by(foreign rep78)
tempfile tofill
gen byte freq = 0
save `tofill'

sysuse auto, clear
contract foreign rep78
gen byte freq = 1

append using `tofill'

gen stat = cond(freq==1, _freq, mpg)
label define freq 1 "frequency" 0 "mean"
label value freq freq

tabdisp rep78 foreign freq, ///
        cell(stat) format(%9.3g)
restore
*------------------- end example ---------------------

Hope this helps,
