that is in the QTableView under that header are short values such as “100” or 
“2” or “1.231”. When the QTableView is rendered the the column with is only as

when calculating the width of the column.

This is with Qt 6.5.3 and 6.6.3.

Hi Mike,

you should be able to reimplement 
https://doc.qt.io/qt-6/qtableview.html#sizeHintForColumn and 
https://doc.qt.io/qt-6/qtableview.html#sizeHintForRow to take the 
https://doc.qt.io/qt-6/qheaderview.html#sectionSizeHint into account.

Cheers,
Volker
