如何在QTableWidget中通过CTRL+click禁用多项选择？

from PyQt5.QtWidgets import QTableWidget, QApplication, QTableWidgetItem
from PyQt5.QtCore import Qt
import sys

class CustomTableWidget(QTableWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        
    def mousePressEvent(self, event):
        if event.modifiers() == Qt.ControlModifier and event.button() == Qt.LeftButton:
            # 禁用多项选择
            self.setSelectionMode(QTableWidget.NoSelection)
            
            # 清除之前的选择
            self.clearSelection()
        
        # 处理其他的鼠标事件
        super().mousePressEvent(event)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    
    tableWidget = CustomTableWidget()
    tableWidget.setRowCount(5)
    tableWidget.setColumnCount(3)
    
    for row in range(5):
        for col in range(3):
            item = QTableWidgetItem(f'Item {row}-{col}')
            tableWidget.setItem(row, col, item)
    
    tableWidget.show()
    
    sys.exit(app.exec_())
