you can still mouse click on the empty cell, marking bug future and EDITORBASE.

I think this has accessibility impact, marking EDITORBASE+ and nsbeta1+ for that
reason, setting milestone to mozilla 1.0

this is not common i dont believe. if the table cell is completely empty 
arrowing would work fine.  Its only with this <nobr></nobr> empty tag inside the 
table cell that confuses key navigation.  I suggest this is not fixed. certainly 
not for EDITORBASE+

In current trunk builds, you can't enter the empty cell at all, pressing the arrow keys. But you can select the empty cell by clicking on it.
I guess bug 389321 might change things for the better here.

We still see incompatibility among browsers. Not quite sure what the expected/right behavior is.
