在javascript中重新排列对象数据

Question

我有一个JS对象需要重新排列才能在HTML表格中正确显示数据。

基本上，我需要从第一个对象集的第一行获取一些属性，并且每个对象集中只有第一个属性来自第一个对象行。这将是新创建的对象中第一个记录的数据。

var testObject =
{
  6:{
    5:{
      0:{ FirstItem: "1-1-1-1", SecondItem: "1-1-1-2", ThirdItem: "1-1-1-3", FourthItem: "1-1-1-4", Year: "2014"},
      1:{ FirstItem: "1-1-2-1", SecondItem: "1-1-2-2", ThirdItem: "1-1-2-3", FourthItem: "1-1-2-4", Year: "2014"},
      2:{ FirstItem: "1-1-3-1", SecondItem: "1-1-3-2", ThirdItem: "1-1-3-3", FourthItem: "1-1-3-4", Year: "2014"}
    },
    10:{
      0:{ FirstItem: "1-2-1-1", SecondItem: "1-2-1-2", ThirdItem: "1-2-1-3", FourthItem: "1-2-1-4", Year: "2014"},
      1:{ FirstItem: "1-2-2-1", SecondItem: "1-2-2-2", ThirdItem: "1-2-2-3", FourthItem: "1-2-2-4", Year: "2014"},
      2:{ FirstItem: "1-2-3-1", SecondItem: "1-2-3-2", ThirdItem: "1-2-3-3", FourthItem: "1-2-3-4", Year: "2014"}
    }
  },
  22:{
    5:{
      0:{ FirstItem: "2-1-1-1", SecondItem: "2-1-1-2", ThirdItem: "2-1-1-3", FourthItem: "2-1-1-4", Year: "2015"},
      1:{ FirstItem: "2-1-2-1", SecondItem: "2-1-2-2", ThirdItem: "2-1-2-3", FourthItem: "2-1-2-4", Year: "2015"},
      2:{ FirstItem: "2-1-3-1", SecondItem: "2-1-3-2", ThirdItem: "2-1-3-3", FourthItem: "2-1-3-4", Year: "2015"}
    },
    10:{
      0:{ FirstItem: "2-2-1-1", SecondItem: "2-2-1-2", ThirdItem: "2-2-1-3", FourthItem: "2-2-1-4", Year: "2015"},
      1:{ FirstItem: "2-2-2-1", SecondItem: "2-2-2-2", ThirdItem: "2-2-2-3", FourthItem: "2-2-2-4", Year: "2015"},
      2:{ FirstItem: "2-2-3-1", SecondItem: "2-2-3-2", ThirdItem: "2-2-3-3", FourthItem: "2-2-3-4", Year: "2015"}
    }
  }
};

所需对象：

var desiredOutput =
{ FirstItem: "1-1-1-1", FourthItem: "1-1-1-4", Year: "2014", FirstItem: "1-2-1-1", FirstItem: "2-1-1-1", FirstItem: "2-2-1-1" }, 
{ FirstItem: "1-1-2-1", FourthItem: "1-1-2-4", Year: "2014", FirstItem: "1-2-2-1", FirstItem: "2-1-2-1", FirstItem: "2-2-2-1" }, 
{ FirstItem: "1-1-3-1", FourthItem: "1-1-3-4", Year: "2014", FirstItem: "1-2-3-1", FirstItem: "2-1-3-1", FirstItem: "2-2-3-1" };

请检查JSFiddle链接与我当前拥有的对象和所需的输出：

我已经尝试了一切，但没有成功。我在我的项目中使用了underscoreJS。
