First, you can use the same approach with the grid that you are using with
SQLFORM, as the grid simply produces a SQLFORM when creating or updating
records. Note, web2py DOM objects have an .add_class() method, so you can
use that instead of manually extracting and updating the "_class" attribute.
Another option is to specify a custom widget for the field in question,
either when the db table is defined or later:
Field('cantidad', widget=lambda f, v: SQLFORM.widgets.string.widget(f, v,
_class='col-sm-3', _maxlength=8))
