如何在swift中的tableview中的didselectrow方法中点击内容视图

我是ios的新手我正在使用表格视图制作一个项目，其中我已经扩展了具有4个内容视图的表格视图单元格 . 当表格仅加载第一个内容视图时，当我选择行时，所有内容视图都会展开 . 但是当我点击第四个内容视图时，我也想要扩展所有内容视图单元格后，我想在第四个视图的tapGESTUREAction方法中访问indexPath.row . 这个扩展Cell的代码包含4个内容视图func tableView（_ tableView：UITableView，numberOfRowsInSection section：Int） - > Int {print（YearArr.count）return YearArr.count; }

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cellIdentifier = "Cell"
        let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier) as! customCell
        cell.selectionStyle = .none
             cell.lblGrossSal.text = EarnArr[indexPath.row]

         cell.lblTotlSal.text = netPayArr[indexPath.row]
         cell.lblmonthhName.text = YearArr[indexPath.row]
            print(selectedIndex,indexPath.row)
        let height = cell.bounds.height
        print(height)
       return cell;
    }

       func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        let cellIdentifier = "Cell"
        let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier) as! customCell
        cell.selectionStyle = .none

        if(selectedIndex == indexPath.row) {

                       return 190;
            return self.calculateHeight(selectedIndexPath: indexPath)
        } else {

                        return 50;
        }
           }
 // fourthView
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        if(selectedIndex == indexPath.row) {
            selectedIndex = -1
                   } else {
            selectedIndex = indexPath.row

        }
        self.expandTableView.beginUpdates()
        //self.expandTableView.reloadRows(at: [indexPath], with: UITableViewRowAnimation.automatic )
        self.expandTableView.endUpdates()


       }
    func calculateHeight(selectedIndexPath: IndexPath) -> CGFloat {
        let cell = self.expandTableView.cellForRow(at: selectedIndexPath) as! customCell
        cell.lblDeductSal.frame = self.cellSummaryLabelFrame(cell: cell, selectedIndexPath: selectedIndexPath)

        return 80 + 35 + 21 + 10 + cell.lblDeductSal.frame.size.height + 30
    }

    func cellSummaryLabelFrame(cell: customCell, selectedIndexPath: IndexPath) -> CGRect {
        print(DeductionArr[selectedIndexPath.row])
        cell.lblDeductSal.text = DeductionArr[selectedIndexPath.row]
        cell.lblDeductSal.numberOfLines = 0
        var labelFrame = cell.lblDeductSal.frame
        let maxSize = CGSize.init(width: cell.lblDeductSal.frame.size.width, height: CGFloat.greatestFiniteMagnitude)
        let requiredSize = cell.lblDeductSal.sizeThatFits(maxSize)
        labelFrame.size.height = requiredSize.height
        return labelFrame
    }
