Hiding zero in ALV(Particular Row/Column alone)

Question

I use ALV Grid  for displaying the output in the tabular form. It has one key field and 4 numeric fields. Always it will have only 7 rows. Now I should not display 0 if the row 4 does not have any values(Since it is a numeric field, by default zero will come). Rest of the rows should contain zero value if there is no value.
If I should not display zero for all the rows, then I can simply pass no_zero = u2018Xu2019 in the field catalog. But this should happen only for the particular row (4th row alone). Please advise me.

Hi Selva,
I am posting a example code, in this some paticular cells of ALV Grid are in editable mode. just analyse this example this may help you..
