Hi,
I want to change the name of the columns in a SimpleList (index unit) or List (power index unit), for example:

So, I want to show Names by "nombre", Lastnames by "apellido", Email by "email", Country by "idPais", Institution by "idInstitucion"... in Persons List (power index unit).
In Countries List (power index unit), the changes are:
Names by "nombres" and Abbreviation by "abbreviation"
Any suggestions?
Again Thanks,
Jose
