st: Combining estimation results and estpost results in esttab

[Stephi Springham <stephi.springham@gmail.com>]

I need to display in the same table, ratios by subpopulation (from the
ratio command) in one column, and in the next column some results from
estpost.

The nearest I can get is using the following, but it doesn't look great!

ratio (_:a/b), over(urban)
estimates store est1

ratio (_:a/b)
estimates store est2

estpost tabstat var, stats(sum) by(urban)
estimates store est3

esttab est1 est2 est3 using "$output/table.csv", ///
   replace cells("b sum") plain noobs


           est1                   est2                   est3
           b          sum        b          sum       b        sum
Urban  78.4                                                       30784
Rural   100.3                                                      89540
Total                              94.4                             120324


What I would love to achieve, is to lose the 'sum' columns for est1
and est2, and lose the 'b' column for est3... is this possible?

And what would be even more magical, move the 'total' ratio from est2
over to the est1 'b' column.

Can anyone please help me?  I am very new to these commands....

Many thanks!
