If I understand you correctly, you use the Table grid to display your collection and from there on, you want to edit at least the “Approved”.
First, you will have to set up a Dynamic Page. THis page will display every item that you click in the table. You can put as many field into that form as you wish, all bound to the Dataset. One of them will be a checkbox called “Aproved”.
Secondly, you will have to link the table to the Dynamic Page, so it knows what to do when a row is clicked (where to go to, which Dynamic Page).

Just work your way thru the examples, most of us did, then you will understand how to change your own project. Good luck.
