Whew! This is getting sort of long,
I might be running out of steam on it.

I'm sort of lost as to how else I can get that piece of data (the row
wrapper) into the FieldList object.

These two main sentences summed up where I think this
might be able to go.

I don't view a table as a group of Field lists.
I view it as a list of rows.

Should you add the concept of the Row in your OO design?
It certainly is an abstraction reflected in your implementation.

I.e. you had a piece of data that served as a row wrapper,
and an abstraction (the loop) that was effectively
operating repeatedly on rows.
This is an operation on a row, but you've got no
abstraction for the row.
      myTable.getFieldList(i).setFormatter(listFormatter);
      myTable.getFieldList(i).xmlWrapper="Data";
      out.println(myTable.getFieldList(i).toML());


Dunno if you actually want the Row class, but perhaps
just some methods in the table class to operate
on the logical concept of a row is something
that would help the thought process.
