I want horizontal lines separating my the levels of my first dimension. I can almost obtain this using by adding the option "spacer" . But spacer gives me blank lines instead of borders between the groups:

Code:
sysuse auto, clear
egen price_n4=cut(price), group(4)
table (rep78 foreign) (price_n4), stat(mean headroom) nototals
collect style row split, delimiter(`" # "') atdelimiter(`" @ "') bardelimiter(`" | "') binder(`"="')  dups(first) position(left) span spacer
collect preview
gives...


price_n4
0 1 2 3

Repair record 1978 1 Car origin Domestic 1.75

2 Car origin Domestic 3.25 3 4

3 Car origin Domestic 3.142857 3.5 2.7 3.357143
3 Foreign 3 2.5 2.5

4 Car origin Domestic 3 2.75 3.625 4
4 Foreign 3.5 2.75 2 2.375

5 Car origin Domestic 2 2.5
5 Foreign 2.75 2 2.625 2.75

but I want borders not lines separating the levels of my first dimension
Code:
rep78
.
