Wait, Light has dawned!
The default display just shows whatever is in the database. If I want to redefine what is displayed, like change the order of the columns or the column heading etc.. I need to go through this edit columns process to create the code to rearrange things.
When I add with this tool I must then go to the object inspector for each of the added fields and define its new properties including what field to display and how to format the data.
Sorry, This will get easier as I get the drift of how things are done.
