Answer 1

You would have to use a cell of appropriate type such as ClickableTextCell or ButtonCell as well as a FieldUpdater .

Basically you can add a FieldUpdater to your column as such:

column.setFieldUpdater(new FieldUpdater<YourObject, String>() {
        @Override
        public void update(int index, YourObject object, String value) {
            Window.open(value, "_blank", ""); //This will open link in a new tab or window
        }
    });

Where value in this case is the url. update() will be called when the column is clicked.
