I just finished a program you might like. The program is a wrapper
for the official -estimates table-. However, it is much more
flexible than -estimates table-. I will send it to 
the SSC archive today, so it probably will be available tomorrow.

Note that -estout- is a general program to export regression 
results. Thus, it is possible to switch styles (tab, tex, html) 
or even define delimiters etc. manually.

-estout- has the eform option

-estout- has options to insert user defined stuff at different places 
in the table (prehead, posthead, prefoot, postfoot). The prefoot-option 
could be used to manually insert information on suppressed variables.

Significance signs are fully customizable in -estout- (including 
number and values of levels) and can be detached if needed. 
Legends can be printed or not.

Note, that that -estout- does not bother setting up the table/tabular 
environment. You would have to use prehead and postfoot options 
to insert the \begin{tabular}{...} and \end{tabular} commands. 
I did not include automatic generation of such stuff because 
I think that it is too much user dependent. However, it should be
real easy to cutomize -estout- to automatically print such stuff.

-estout- currently has the parentheses option. Extending the otion to
embrace the se- or t-values with whatever you like is on my to-do-list.
