QT Remove Horizontal header of table

Question

I have a function setHorizontalHeader,which adds a header to the table by adding header items one by one using setHorizontalHeaderItem.If I want to delete a header which function should I use? Looks that takeHorizontalHeaderItem() suits, but it removes the item without deleting it. After caling takeHorizontalHeaderItem for all items I get the header with numbers inside it. I need to entirely delete the header (data + cells) – How do I implement it correctly?

The horizontalHeader in a QTableView is a widget like any other. If you want to hide it, just call its hide() member (which is a slot too).

 view->horizontalHeader()->hide();

This hides the whole header bar. It doesn't destroy or otherwise change the contained header items.

When you want the header to be displayed again, simply show() it. The header items will remain as they were before the hide() (unless you've changed them in between).

 view->horizontalHeader()->show();

(Works for the vertical header too, obviously.)
