tab order in table view

I have a table view that starts out empty, but is populated by files being dragged in. The 3rd column “station numbers” is not populated. The operator needs to insert numbers in here. Is there a way to set this up so hitting tab will only enter this 3rd column starting with data row 1 and working its way down thru the last data row?

example, hitting tab once will set the cursor in data column 3 of data row 1 of thedatasource. Hitting tab again will move the cursor to data column 3 of data row 2 of thedatasource
