Output t-statistics in difference in difference estimation

[Farhan Hasnat]

I ran the following difference in difference estimation and used the author defined output code using outreg2. However, I am trying to show t-stat instead of standard error also asterisks for p-value significance level. I tried adding t-stat into the code but does not seem to work. Any help would be great

 diff ABS_DA_w, t(AIC_GIC) p(year_dum)
