如何在PyQt5中单击按钮时从表中删除复选框？

from PyQt5.QtWidgets import QApplication, QMainWindow, QTableView, QPushButton
from PyQt5.QtGui import QStandardItemModel, QStandardItem
from PyQt5.QtCore import Qt

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

        self.model = QStandardItemModel()
        self.model.setColumnCount(2)
        self.model.setHorizontalHeaderLabels(['Name', 'Selected'])

        self.table_view = QTableView(self)
        self.table_view.setModel(self.model)

        self.button = QPushButton('Delete', self)
        self.button.clicked.connect(self.delete_selected_row)

        self.setCentralWidget(self.table_view)
        self.addToolBar(Qt.BottomToolBarArea, self.button)

        self.populate_table()

    def populate_table(self):
        names = ['John', 'Jane', 'Mike', 'Emily']
        for name in names:
            item = QStandardItem(name)
            item.setCheckable(True)
            self.model.appendRow([item, QStandardItem()])

    def delete_selected_row(self):
        selection_model = self.table_view.selectionModel()
        selected_indexes = selection_model.selectedRows()

        for index in selected_indexes:
            self.model.removeRow(index.row())

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