1. 在cell的content View上放一個UIView控制元件，設定cell高度與uiview的高度為300
2. 在uiview上再新增一個UIImageView，設定左右靠邊，高度設定為400
3. 設定圖片的填充模式為aspectFill【放張大圖】

程式碼設定：

1. 設定tableviewHeight = 300
2.

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell
 
(withIdentifier: "reuseIdentifier", for: indexPath)

        // Configure the cell...
//        for cell in tableView.visibleCells {
            let coverView = cell.contentView.viewWithTag(100)
            let image = coverView?.viewWithTag(200)

            let rect = coverView?.convert((coverView?.bounds
 
)!, to: nil)

            var y = UIScreen.main.bounds.size.height - (rect?.origin.y)! - 600
            y *= 0.2
            if y > 0 {
                y = 0
            }
            if  y < -100 {
                y = -100
            }
            image?.frame.origin.y = y

//        }

        return cell
    }
 

3.

    override func scrollViewDidScroll(_ scrollView: UIScrollView) {
        for cell in tableView.visibleCells {
            let coverView = cell.contentView.viewWithTag(100)
            let image = coverView?.viewWithTag(200)

            let rect = coverView?.convert((coverView?.bounds)!, to: nil)

            var y = UIScreen.main.bounds.size.height - (rect?.origin.y)! - 400
            y *= 0.2
            if y > 0 {
                y = 0
            }
            if  y < -100 {
                y = -100
            }
            image?.frame.origin.y = y

        }
    }

動畫效果如下：
