Edit single field in single line in ALV

Question

Dear experts,
I have an ALV with many lines.
I need to edit one field in a few of those lines, depending on the data. How can I do that? I aldeady used the EDIT parameter of fieldcat, but it changed the whole column of the table.
Please help.
Thanks,
Roxani

Hi again,
1. Just for info purpose.
2. We can use colours   
3. Not only the full row color,
  we can also manipulate the color in each cell.
4.
IMPORTANT THINGS
a. Extra field in internal table
clr TYPE slis_t_specialcol_alv,
(this field will contain the colour codes)
b. assign fieldname to alv layout
alvly-coltab_fieldname = 'CLR'
c. work area for colour
DATA : clrwa TYPE slis_specialcol_alv.
d. Populating the color
Once again
Loop at ITAB.
*********logic
if itab-field < 0 "---negative
clrwa-fieldname = 'FIELDNAME'. "<--- FIELDNAME FOR COLOR
clrwa-color-col = 6. <------- COLOUR 0-9
APPEND clrwa TO itab-clr.
MODIFY ITAB.
endif.
ENDLOOP.
5. just copy paste in new program
6.
