There is more than one way to do it. 

Here is an alternative. 

gen Variable = "" 
gen dfuller = "" 
local i = 0 

foreach v in m1 m2 consump { 
	local ++i 
	replace Variable = "`v'" in `i' 
	dfuller `v' 
	replace dfuller = string(r(Zt), "%6.4g") in `i' 
} 

tabdisp Variable, cell(dfuller) in 1/`i' 

Disadvantages of this: 

1. The results are not aligned with your existing data. Could
lead to misunderstanding. 

2. Will be problematic if #results > _N. 

3. -tabdisp- is limited to 5 cell variables. 

Advantages of this: 

1. Keeps results together with existing data. 

2. Further analysis, graphing, etc., often easy. 

3. Can control formats desired at source. 

4. Can elaborate, e.g. by using variable labels.
