This is described in the Field constructor documentation, but I'm not sure
there are any examples in the book using this.

This seems to work:
form.custom.widget.ftest1['_maxlength'] = 14
(I tested this on a string field)
You can also use a lambda to instruct your widget in the Field()
constructor.
My research found Anthony's post from a year ago March:
<URL:https://groups.google.com/d/msg/web2py/7KNT72mOTYg/v8takmfGZQgJ>
"maxlength" is a standard HTML attribute, and SQLFORM respects that. It
should apply to the string, text, password, and maybe also to the integer
and double/decimal fields. The validators in the model file will only be
applied on submission, I believe. Adjusting the size of the input box
involves a separate attribute, which would be '_size', but that doesn't
seem to work unless you specify the formstyle explicitly; it works with
either 'table2cols' or 'table3cols' in my quick tests.
