I've got some old code that looks like this...from memory it does what you
want. This is in my QTreeView __init__:
self.header().setSectionResizeMode(QtWidgets.QHeaderView.Fixed) # This is
setResizeMode in PySide1
for i, c in enumerate(self.model().columns):
self.header().resizeSection(i, c.pixelWidth)
