求助tableWidget添加QLineEdit控件取值问题

请朋友帮我看看哪里设置不对，我添加了正则，单元格数据不能响应，取不到值。
　　　　　　 for sc1 in range(len(stm)):
                value=int(list_text[wz][sol1+1])/100
                if value==0:
                    newItem=QTableWidgetItem('')
                else:
                    newItem=QTableWidgetItem('{:,.2f}'.format(value))
                newItem.setForeground(QColor(0,0,0))
                pDoubleValidator=QDoubleValidator()
                pDoubleValidator.setNotation(QDoubleValidator.StandardNotation)
                pDoubleValidator.setDecimals(2)
                newItem.setTextAlignment(Qt.AlignRight|Qt.AlignVCenter)
                self.tableWidget.setItem(rec ,stm[sol1], QTableWidgetItem())
                self.ceil=QtWidgets.QLineEdit('{:,.2f}'.format(value))
                self.ceil.setValidator(pDoubleValidator)
                self.tableWidget.setCellWidget(rec ,stm[sol1],self.ceil)
                self.ceil.editingFinished.connect(self.eFinished)
                self.ceil.setStyleSheet("background:transparent;border-width:0;border-style:outset")
                self.ceil.setAlignment(Qt.AlignRight)
                sol1=sol1+1
