Button in Table view

Hi Gurus,

I have two columns(date and status) in table view in WDP for Abap application. In the corresponding source table, if date is 00/00/0000, then I need to populate an approve button in the status column of table view, otherwise the actual date has to be populated from the table. After populating the approve button, if its clicked the system date should be displayed in the date column and the approve button should be disappeared.
