app.setStyleSheet("QTableView::item { padding: 5px;}") PyQt5 not working properly. How to fix?

Question

css

Hello, I wanted to add spaces between PyQt table elements. Here's the line of code.

app.setStyleSheet("QTableView::item { padding: 5px;}")

Instead of divisions between the cells of the table, it turned out to be simply an increase in the cells themselves.

Here is a picture of what it should look like


Thank you in advance for helping me solve the problem
