Another Base Form question

[Dan Lewis]

     When creating a Base form using Design View, I use the Control 
tool to select the properties I want for a field. Clicking it opens the 
Properties dialog. In the Data tab, the "Type of list contents" property 
contains these choices: Value list, Table, Query, SQL, SQL [Native], and 
Tablefields. I can use these: Value list, SQL, and SQL [Native].
     Selecting Table lists the available tables in the "List contents" 
property. But selecting the appropriate table does not give me a 
dropdown list when I open the form. (I save my changes, close the form, 
save the database, and open the form.)
     General question: What purpose does these properties serve? 
(Table, Query, and Tablefields) Any examples on how these can be used?
