            for col_num, col_data in enumerate(row_data):
                self.query1_window.table_widget.setItem(row_num, col_num, QTableWidgetItem(str(col_data)))
        self.query1_window.show()

class QueryResultWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.setFixedSize(800, 600)
        self.table_widget = QTableWidget()
        self.table_widget.setEditTriggers(QTableWidget.NoEditTriggers)
        self.table_widget.setSelectionBehavior(QTableWidget.SelectRows)
        layout = QVBoxLayout()
        layout.addWidget(self.table_widget)
        self.setLayout(layout)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    mainWindow = MainWindow()
    mainWindow.show()
    sys.exit(app.exec_())

主要是在 `show_query1_result` 方法中添加了一个输入框，用于输入要筛选的员工ID，然后根据输入的ID从数据库中查询数据并展示在表格中。注意要导入 `QInputDialog`，这是一个用于获取用户输入的对话框。
