Hello jlu,
I’ve got an answer from the dev team. The createwidget version does not work, because the last column (with buttons) does not exist in the time of column’s creation that’s why an error is thrown and this is not an issue/bug. That’s the way createwidget is working. Therefore you could either use cellsrenderer as in the example or put the buttons column in first place. Also we’ve updated the cellsrenderer example (vertical header lines are removed).
Best Regards,
