是否可以在QTreeWidget列中对数字进行排序？

python复制from PyQt5.QtWidgets import QApplication, QTreeWidget, QTreeWidgetItem
from PyQt5.QtCore import Qt
import sys

app = QApplication(sys.argv)

tree = QTreeWidget()
tree.setColumnCount(1)

# 创建一些包含数字的项
items = [QTreeWidgetItem(tree, [str(i)]) for i in range(10, 0, -1)]

# 设置每个项的数据角色为Qt.UserRole，值为对应的数字
for i, item in enumerate(items):
    item.setData(0, Qt.UserRole, 10 - i)

# 设置排序为按照Qt.UserRole的值进行，即按照数字进行排序
tree.sortByColumn(0, Qt.AscendingOrder)

tree.show()

sys.exit(app.exec_())
