“Ui\u Form”对象没有属性“CULOMN\u 5”

Question

我用self.ROW更改了self.CULOMN\u5，但仍然是相同的错误，所以都在CULOMN\u5上

im不断获取'Ui\u Form'对象没有属性'CULOMN\u 5'错误

def    double_table(self):
        for currentItem in  self.tableWidget.selectedItems():
            self.CULOMN_5=currentItem.column()
            self.ROW_5=currentItem.row()
        #if u ckick on column (i,4) i want to get result   
        if  (self.CULOMN_5==4):
            self.l=self.tableWidget.item(self.ROW_5,2)
            self.w=self.tableWidget.item(self.ROW_5,3)
            self.l=self.l.text()
            self.w=self.w.text()
            ##print(self.l,'  ',self.w,' ',type(self.w),' ',type(self.l))
            #Multiplication of two column at the same row 
            if  (self.l!='' and self.l!=None  and self.w!='' and self.w!=None):
                self.m=float(self.l)*float(self.w)
                self.tableWidget.setItem(self.ROW_5,4,QTableWidgetItem(str(self.m)))
            else:
                self.tableWidget.setItem(self.ROW_5,4,QTableWidgetItem("Error"))
        else:
            pass

我想将同一行的两列相乘，并显示该行最后一列的结果
