Hi Steve,
The first thing I would check is whether the cells are actually 'blank' or if their content is there but displayed as 'white' text. Click individually on a selection of cells and check the contents of the entry box above the table.
If the content is there, select the whole table and change the text colour to black, using the color well in the Text section of the Forma bar.
Other than that, the only suggestions I can make is to ensure that you have updated Mountain Lion and Numbers both to their latest versions. For Numbers '09, I think that's v4.3.
Regards,
Barry
