pyqt5 列表内添加按钮

我们想在操作列表内添加按钮，例如查看、修改、删除

1、定义添加按钮的方法

# 列表内添加按钮
    def buttonForRow(self,id):
        widget=QWidget()
        # 修改
        updateBtn = QPushButton('修改')
        updateBtn.setStyleSheet(''' text-align : center;
                                          background-color : NavajoWhite;
                                          height : 30px;
                                          border-style: outset;
                                          font : 13px  ''')

        updateBtn.clicked.connect(lambda:self.updateTable(id))

        # 查看
        viewBtn = QPushButton('查看')
        viewBtn.setStyleSheet(''' text-align : center;
                                  background-color : DarkSeaGreen;
                                  height : 30px;
                                  border-style: outset;
                                  font : 13px; ''')

        viewBtn.clicked.connect(lambda: self.viewTable(id))

        # 删除
        deleteBtn = QPushButton('删除')
        deleteBtn.setStyleSheet(''' text-align : center;
                                    background-color : LightCoral;
                                    height : 30px;
                                    border-style: outset;
                                    font : 13px; ''')


        hLayout = QHBoxLayout()
        hLayout.addWidget(updateBtn)
        hLayout.addWidget(viewBtn)
        hLayout.addWidget(deleteBtn)
        hLayout.setContentsMargins(5,2,5,2)
        widget.setLayout(hLayout)
        return widget

2、在向tableWidget里添加数据时插入即可

for row_number, row_data in enumerate(rsdata):
    self.ui.tableWidget.insertRow(row_number)
    for i in range(len(row_data)+1):
        if i<len(row_data):
            self.ui.tableWidget.setItem(row_number, i, QtWidgets.QTableWidgetItem(str(row_data[i])))
        # 添加按钮
        if i==len(row_data):
            # 传入当前id
            self.ui.tableWidget.setCellWidget(row_number, i,self.buttonForRow(str(row_data[0])))
