Thanks for your report. I could reproduce it. I guess in fact we have two 
problems here:
1. a row should always have at least the height of a character
2. the cells should not be empty, but they should display NULL (in italics) to 
indicate this cell is NULL and not empty or something

Because at the moment if you do this:
SELECT NULL, ''
You cannot make a difference between the value of the first and second column.
Note that this works correctly if you browse a table. Seems to be another 
problem with redundant code here :-(

I just fixed this issue in svn. Now empty strings echo   to make sure the row 
height is not zero. And NULL gets displayed as NULL (in italics) now also in 
the sql tab.
We have more or less the same code 3 times here:
- action=table_sql
- view=sql
- action=row_view
share a big bunch of code. This issue was only done in case of action=row_view, 
I now also did it in the other two cases. We should really reduce redundant 
code here. I will open another issue for this particular case.
