Hi,
In that order listing you can display some "order custom field" (by configure them to be display there).
You can't display item custom fields unless you perform yourself some modifications in the view (thanks to a view override).
It is not extremely complex but it requires some development/PHP skills in order to load the order items and analyze the content to fill your new table cell.
