How to hide cellWidget of QTableWidget?

How can I hide a cellWidget of (row,column) in QTableWidget?

this->cellWidget(0, 6)->hide();
this->cellWidget(0, 6)->setVisible(false);

I called these two methods both no use.

Hi. This seems to be a bug, still unresolved.
For a possible workaround, have a look at

If it is really a bug you can check on JIRA using the same account as here in the forum. JIRA is the only place where bugs have to be reported to.
Neither the forum here nor any other place is monitored for potential bugs. If it is not reported, it can't be fixed.

This is a long-standing bug which has been reported several times already (some of which have been closed as duplicates, like this one: https://bugreports.qt.io/browse/QTBUG-22490.).

The proposed solution is in the link I provided. Apparently, you must subclass QTableWidget and override the paintEvent() method to hide the cells every time after the actual painting is done.

DerivedQTableWidget::paintEvent(QPaintEvent * e)
{
   QTableWidget::paintEvent(e);

   // do the hiding here
}

I have not tested this though...
