Hello Stata Experts!

Currently I am lost at "just" finding the right output form/ format, which is very frustrating after a long data analysis!
I am running multiple regressions over 11 groups - now I want to create the perfect output table for my article in LaTex.

Ultimately, I would like to have an output of:

Group 1 Group 2 Group 3
Model 1
Model 2
Model 3

where the content of the table is the regression's constant (_b[_cons]), below the t-statistic and stars for significance. I am aware that I can build this writing my own program and using the stata command "table" for the results, however I then lose all options to have a nice "article style" output with stars, correct lines etc. Is there any way to use one of the more powerful estout commands (or similar) to that?

Thank you a lot!
Tobias

Im using stata 16.1

Model 1: reg Eret MKT
Model 2: reg Eret MKT SMB HML
Model 3: reg Eret MKT SMB HML RMW CMA

Groups are given by ID_portfolio (from 11 to 21)
