No need to compromise the data. Simply apply a number format in the
worksheet cells that suppresses display of zero, something like

0;;;

and the zero will be hidden in the worksheet and in the data table.

This works in 2007 and in Classic Excel.

I never use data table, so this is just what I found be experimenting.
The dialog for formatting data tables has no provision for formatting
the numbers

I made some data with B5 as a blank cell and generated a chart for it.
The data table in the chart had the entry for B5 blank. But if I had a
formula like =IF(test,"", number) then B5 might look blank but a 0 shows
in the data table.

However a formula as =IF(test, NA(), number) gives a blank in the data
table
If you do not like the look of #N/A in the data series, then use
conditional formatting in the form =ISNA(cell ref) and make the font the
same colour as the cell background to hide it.
