How to set Width and Height of QTableWiget's Column and Row .

I am making use of QTablewidget.
I want to have row height same as the widget->height which is added using table->setCellWidget();

Same goes with Column.Column width same as widget->width.

How should i obtain this without actually getting the width and height from the widget and then setting it individually.

Any help would be appreciated .
Thanks.

tbalewidget->setColumnWidth();
tbalewidget->horizontalHeader()->setFixedHeight();
