No.

Now that the short answer is dealt with, here's the slightly longer one.

The Alias is created at the time the table is created, that's because we actually create a real table in the backend database your Joomla website is running on. The alias is the actual column name in the table in the database, it's also used to for the CSS class label for the column.

To answer the next logical question - yes in a future version you may be able to change the alias. Like all feature requests it really depends on how much time we can afford to spend on the EasyTable component.

EasyTable Pro supports the modification of all table structure elements including the alias of a field. The same limitation to the alias value as it is still used as the actual column name in the table in the database and the CSS class label for the column.
