如何使用swift中的storyboard将数据填充到可扩展的tableview中

Question

我想添加一个可扩展的tableview。单击单元格后，它应该展开其中的另一个tableview。 我正在分享屏幕截图。

现在我想点击单元格之后它应该扩展到所有数据的高度。并且视图应该是这样的。

我的代码是

     func ParseJSON(){

    var MenuList = [Menu]()

    Alamofire.request(.GET, myUrl)
        .validate()
        .responseJSON { response in
            switch response.result
            {
            case .Success:
                if let value = response.result.value {
                    let json = JSON(value)
                    // print("JSON: \(json)")
                    for entity in json{
                        print(entity)

                    }

                }
            case .Failure(let error):
                print(error)
            }
    }

}

我的模态类是

      import UIKit
        class Menu {
          var id: Int?
         var name: String?
         var image: UIImage?
         var coupon: Int?
         var icon: UIImage?
         var order: Int?
         var aname: Int?
         var options: Int?

init(id:Int,name:String,image:UIImage,coupon:Int,icon:UIImage,order:Int,aname:Int,options:Int){
        self.id = id
        self.name = name
        self.image = image
        self.coupon = coupon
        self.icon = icon
        self.order = order
        self.aname = aname
        self.options = options


    }
   }

如何在tableview中填充菜单名称。之后单击此表视图将扩展到我要显示子类别名称的整个数据的大小。

查看json数据：

     [
      {
         "id": "244",
          "name": "PIZZAS",
          "image": "",
          "coupon": "1",
          "icon": "",
          "order": "1",
          "aname": "",
          "options": "2",
          "subcategory": [
           {
            "id": "515",
            "name": "MARGARITA",
            "description": "Cheese and Tomato",
            "image": "",
            "icon": "",
            "coupon": "1",
            "order": "1",
            "aname": "",
            "options": "2",
            "item": [
                        {
                           "id": "1749",
                           "name": "9 Inch Thin & Crispy Margarita",
                           "description": "",
                           "price": "3.40",
                           "coupon": "1",
                           "image": "",
                           "options": "2",
                           "order": "1",
                           "addon": "495",
                           "aname": "",
                           "icon": ""
                    }]
              }]
      }]
