First, don't use Crud, as it has been deprecated. Just use SQLFORM.
To apply special formatting to required fields, you can either create
custom widgets or create a custom formstyle function that generates the
desired HTML markup.
A custom widget might look like this:
Field('name', widget=lambda f, v: SQLFORM.widgets.string.widget(f, v, _class
='required'))
Then add a CSS rule for the "required" class.
Creating a custom formstyle function is more complex. You can check out the
framework code for an example:
