QTableView - CSS Problem

So, I'm trying to modify the QTableView with CSS for a darker look, but there's one area that remains white and I can't change it. Red area marked in the image below:

If anyone could help with this, it would be highly appreciated. The CSS used is this:

QTableView {
background-color: qlineargradient(spread:pad, x1:0, y1:0, x2:0, y2:1,
stop:0 #363433, stop:1 #171614);
color: #d1cfcd;
selection-background-color: #314159;
gridline-color: transparent;
}

QTableView QTableCornerButton::section {
background-color: #4d4b48;
}
