Prevent edit on rowgroup

I'm using Editor and Rowgroup.

This is my event:
$('#dataTablesEditor').on( 'click', 'tbody td:not(:first-child)', function (e) {
editor.inline( table.cell( this ).index(), {
onBlur: 'submit'
} );
} );

How can i disable edit when clicking on the rowGroup tr?
Now i got an error:
ught Error: Cannot edit more than one row inline at a time
