[web2py] SQLFORM.factory tablename doesn't affect submit row

[Massimiliano]

>From something like that:

   form = SQLFORM.factory(
        Field('mydate', 'date', label='Data carico', requires=IS_DATE()),
        table_name='mytable',
        _id = 'myform'
    )


I got:

[...]
<tr id="mytable_mydate__row" style="display: table-row; ">...</tr>
<tr id="submit_record__row">....</tr>
[...]

The submit row doesn't take the tablename....
Is it normal?
