title: Appending stored estimates to tex output -- without separate tables/row headers
body: <p>Issue: concatenating estimation results that arise in different programs into TeX output without repeating row header information and separating the table.</p>
  
  <p>MWE below--but imagine my constraint is that I cannot combine the different estimations into the same program (different datasets, lots of processing in between) but nonetheless want the models to appear in the output like they do when storing estimates from specifications within the same program; i.e., I want to append to the existing output, written to disk in the first step, seamlessly and to appear in-line with common row labels (as applicable here), footer, proper column numbering, etc). Based on the nature/structure of TeX this might not be possible directly, but perhaps someone knows of a workaround?</p>

  <pre><code>sysuse auto, clear
  g ln_price = ln(price+1)
  eststo clear
  eststo: reg ln_price mpg
  esttab _all using temp.tex, style(tex) append
  *note that temp.tex clearly shows the appended regression estimates will be compiled in a different "table" separate from the first set, rather than in-line
