By default, all properties in the Customer class are added to the Selected list.
Properties in this list are shown in each row in the table. For our example, we only
want to display the firstName , middleName , lastName , and email properties,
therefore we need to remove all but these properties from the Selected list. After
organizing the properties by selecting them and clicking the Up and Down buttons
as appropriate, we should have only the desired properties in the selected window
and in the correct order.
After clicking OK , we can see that our table has changed in the design window. The
property names are shown as column headers, and the placeholder text abc is shown
as a dummy value representing the dynamic data that will be shown in each cell.
