如何对齐qtreewidget列的文本："...qtreewidgetitemdata“而不是"qtreewidgetitemdata..."？

from PyQt5.QtWidgets import QApplication, QTreeWidget, QTreeWidgetItem, QMainWindow
from PyQt5.QtCore import Qt

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.treeWidget = QTreeWidget(self)
        self.treeWidget.setColumnCount(2)
        self.treeWidget.setHeaderLabels(["Column 1", "Column 2"])

        # 创建QTreeWidgetItem并设置文本对齐方式
        item = QTreeWidgetItem(self.treeWidget)
        item.setText(0, "Item 1")
        item.setTextAlignment(0, Qt.AlignLeft)  # 左对齐
        item.setText(1, "Item 2")
        item.setTextAlignment(1, Qt.AlignRight)  # 右对齐

        self.setCentralWidget(self.treeWidget)

if __name__ == '__main__':
    app = QApplication([])
    window = MainWindow()
    window.show()
    app.exec_()
