Adding a ratio across rows in -table-

table (foreign) (rep78), stat(mean length) nototals stat(proportion, across(foreign))

I want to generate a row that represents the division of the means in Row 1 / Row 2. How can I solve this? -stat(proportion) does not solve this.

--------------------------------------------------------------------
| Repair record 1978
| 1 2 3 4 5
-------------------+------------------------------------------------
Car origin |
Domestic |
Mean |
Length (in.) | 189 199.375 197.8889 204.4444 160
Proportion | 1 1 .9 .5 .1818
Foreign |
Mean |
Length (in.) | 159 165.2222 172.4444
Proportion | .1 .5 .8182
--------------------------------------------------------------------

The final row should have, for example in column 5, 160/172 = 0.93
