Thanks for the direction, Gary. :)
Getting a Choice field working in doctests was quite a
challenge. It now fails as only as a zc.table
FieldColumn. I'm including the relevant doctests and
tests.py
I apologize in advance for the verbose post. :)

Email Address
<input class="textType" id="form.email"
name="form.email" size="20" type="text"
value="bob at zope.com" />
Salutation
<div>
<div class="value">
<select id="form.salutation"
name="form.salutation" size="1" >
<option selected="selected" value="Mr">Mr</option>
<option value="Ms">Ms</option>
</select>
</div>
<input name="form.salutation-empty-marker"
type="hidden" value="1" />
</div>
<input type="submit" id="form.actions.apply"
name="form.actions.apply" value="Apply" class="button"
/>
We'll define columns that allow us to display and edit
name and
email addresses.
>>> from zc.table import fieldcolumn
>>> class ContactColumn(fieldcolumn.FieldColumn):
... def getId(self, item, formatter):
... return fieldcolumn.toSafe(item.id)
>>> columns =
(ContactColumn(MyForm.form_fields["name"]),
...
ContactColumn(MyForm.form_fields["email"]),
...
ContactColumn(MyForm.form_fields["salutation"],)
... )
Now, with this, we can create a table with input
widgets. The columns don't
need a context other than the items themselves, so we
ignore that part of the
table formatter instantiation:
>>> from zc import table
>>> import zope.publisher.browser
>>> request = zope.publisher.browser.TestRequest()
>>> context = None
>>> formatter = table.Formatter(
... context, request, contacts,
columns=columns, prefix='test')
>>> print formatter()
<table>

<tr>
<th>
Name
</th>
<th>
Email Address
</th>
</tr>
</thead>

<tr>

<input class="textType" id="test.1.name"

This is a little messy, alot of setup goes into making
Choice fields work in doctests. Most of it was
shamelessly pasted from Daryl Cousins work.
