In a table you can not. Records in a table are like a barrel of bricks, in
no exact order. You order them in a query by sorting or report by using the
Grouping and Sorting.
So to make sure the records are displayed in an order you desire there needs
to be a field that you sort on. You can add such a field and not display it.
A suggestion would be a number field set to double and number each
incrementing by 10 so as to add the in-betweens.
