I have a problem with the extendedSelection of my QTableView. The Problem is that i have some whitespace around my columns and rows and when i click this whitespace the highlighting of my selected Fields is lost. Its not ocurring when i click somewhere else in my application, only in the whitespace. Also when i set the selection mode to SingleSelection it works just fine.
here is a short gif to illustrate the problem https://gyazo.com/8e4ae161aaff25a4afa1b588579ddd01
