Try
. estimates table *, equations(y=1)
which forces Stata to match up the first equations and label them with the
name of the dependent variable, -y-.
-xtmixed- labels the first equation, the fixed portion, of the model with the
name of the dependent variable, as most Stata commands do. -regress-, on the
other hand, is an older command that does not label the equation. When
displaying coefficients from -regress-, -estimates table- uses an underscore
to denote the lack of such a label.
What I suggest above works around this.
