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 sys
class 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_Dialog
def __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 world
self.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
