I'm confused as to if your prior comment was how I instantiate the Table
object or how I'm formatting the ML or both.
--- end of excerpt ---
I wasn't commenting about the instantiation, only the fact
that generating the ML is probably a behavior of the
table instead of a behavior of the user of a table.

Re: encapsulate the looping.

Yeah, but actually, this is a good thing.
Plus, I think it does more than that.
It helps encapsulates the nastiness about accessing table internals
(fields) directly, and the logic of generating markup language
from a table (behavior of a table).

The more you can change the:
  "using object1, get a contained object from it and use or
   modify the contained object"
into
  "using object1, use or modify object1"
the better OO design you have.

In general:

By modifying or using a contained object, you are actually
modifying or using the container (in this case), and you are
theoretically bypassing things the container should know about
and have control over.

Its not clear to me if in this case a Field is something
that actually should stand alone and the table cares not
what you do with its fields.
