Displaying "0" in a TDBEdit cell

I have a single TDBEdit componenet on a form, a single TDataSource, and
a single TTable pointing to a Paradox 5.0 table I created with the
Database Desktop.  Whenever I enter a 0 into a field, the DBEdit
component displays a blank.  In code, this field evaluates to a 0, and
the Database Desktop shows it as a 0 also.
How can I get the DBEdit component to show this value as a 0 instead of
a blank?
