The notify 'to email field = table field all rows' does not yet support this.
but set up a (hidden) text field (set the character limit accordingly) and then on the table object 'row looses focus' run a set field script to write to this text field..
Table email field - current Row
+
;
+
value of text field
the text field will then contain all the email addresses in the format of mail1@mail.com;mail2@mail.com;mail3@mail.com etc .. and then setting the notify action to this text field will ensure all these email addresses are notified
