Checkboxes to select an entry in a grid (GWT)

Basically, I want to create a table like this:

I created a grid, and added the text values, and the checkboxes. Exactly like in your email box, where you select some mails, and delete them or mark spam.

This is what I have done till now:

Grid grid = new Grid(4, 3);

        for (int i = 0; i < jsonArray.size(); i++) {

            JSONObject jsonValue = json开发者_如何学编程Array.get(i).isObject();
            String lid = jsonValue.get("id").isString().toString()
                    .replace("\"", " ").trim();
            String email = jsonValue.get("email-id").isString().toString()
                    .replace("\"", " ").trim();
            grid.setWidget(i, 0, new CheckBox());
            grid.setHTML(i, 1, lid);
            grid.setHTML(i, 2, email);
            tabDataAll.add(grid);

        }

My question is: Is this the correct way to it? If yes, how can I say, on a click of a button, delete the selected rows?

Also, it would be an added bonus/advantage if I am able sort the columns.

Thanks a lot.
