save button focus when there is no next cell

[rallesaid]

if I add a new row, and complete all fields, how can give focus to the Save button?, currently pressing enter or tab, the editor is maintained in the last cell when this is located in the last row.

I forgot to mention that the options
editModel: {
            keyUpDown : false,
            allowInvalid : true,
            onSave : 'nextEdit',
            onTab : 'nextEdit',
            onBlur : 'validate',
        },

There is no inbuilt option to do it, you have to do it manually by listening to keydown event in editor and set focus on save button when there is no next cell.
