Hey I have two small questions

1) How to end a nested table and start a new one?
2) How to export Adjusted R squared. I tried statistic(a_r2) but it did not export it in the final regression tables

Code:
asdoc reghdfe p_m ntc_change l.p_m did ///
l.ln_a l.l  if list==1, ///
absorb(cc industry_year_fe) add(Firm FE, Y, Industry X Year FE, Y, Controls, Y) ///
nest append save($results/Regression_results.doc)

Thanks
