Remember the field editor defaults to a shared instance of NSTextView basically
that is owned by the window.
You can always create a unique one and assign it to your text fields.
This is a bit more heavy weight than the simpler delegate approach but also
gives complete control while allowing you to use the default field editor for
text fields outside your table.
Though the delegate approach should give you just the same ability if you check
where the text field belongs in some way.
