基本原理就是作个子类继承生成的界面，在子类里写代码
工程结构
dialog_ui.py 界面子类
from PyQt5 import QtCore, QtGui, QtWidgets
from PyQt5.QtGui import QStandardItemModel, QStandardItem, QColor, QFont
from PyQt5.QtCore import Qt
import Ui_dialog
import sysclass myDialog(Ui_dialog.Ui_Dialog):#继承自UI_Diglog类，注意我把UI_Dialog放在了untitled.py中，如果你把这个类放在了XXX.py文件中，就应该是XXX.UI_Dialogdef __init__(self,Dialog):super().setupUi(Dialog)#调用父类的setupUI函数self.pushButton.clicked.connect(self.helloworld)#将按钮点击事件和helloworld函数绑定model = QStandardItemModel(5, 7)# 设置水平表头标签model.setHorizontalHeaderLabels(['设置值', '板卡1', '板卡2', '板卡3', '板卡4', '板卡5', '板卡6'])model.setVerticalHeaderLabels(['电压', '电流', '功率'])# 填充表格数据for row in range(5): # 遍历行for column in range(7): # 遍历列# 创建一个QStandardItem对象，表示单元格内容item = QStandardItem('Item {row}, {column}')# 将单元格内容添加到模型的指定位置model.setItem(row, column, item)self.tableView.setModel(model) def helloworld(self):#label上显示文字hello worldself.label.setText("hello world")if __name__ == "__main__":app = QtWidgets.QApplication(sys.argv)MainWindow = QtWidgets.QMainWindow()ui = myDialog(MainWindow)#注意把类名修改为myDialog#ui.setupUi(MainWindow) myDialog类的构造函数已经调用了这个函数，这行代码可以删去MainWindow.show()sys.exit(app.exec_())
界面及转换后的界面代码Ui_dialog.py
