1. Create a new shapefile with 1 integer, 1 real and 1 string field.
2. Digitize a single feature, don't fill the table.
Each fiels has value "0" forced, although you have not entered it. Editing table also does not let you have the cell empty; it force "0" as well.
I don't think it is a limitation of DBF - using DBF driver in GRASS I can have empty cells in the table, for any datatype.
