覆盖QTableAbstractModel 的headerData 方法以设置列和行名称
def headerData(self, section: int, orientation: PySide6.QtCore.Qt.Orientation, role: int = ...):
#for setting columns name
if orientation == Qt.Horizontal and role == Qt.DisplayRole:
return f"Column {section + 1}"
#for setting rows name
if orientation == Qt.Vertical and role == Qt.DisplayRole:
return f"Row {section + 1}"
