我正在尝试转换来自数据库的对象的平面数组，以提供给需要嵌套结构才能管理可扩展子行的反应表。

我制作了一个 CodeSandbox ，它非常不言自明：

基本上，我的原始数据的结构如下：

  [
    {
      code: "A0",
      parent: ""
    },
    {
      code: "A01",
      parent: "A0"
    },
    {
      code: "A011",
      parent: "A01"
    },
    {
      code: "B0",
      parent: ""
    },
    {
      code: "B01",
      parent: "B0"
    },
    {
      code: "B011",
      parent: "B01"
    }
  ]

我想将其转换为以下结构：

  [
    {
      code: "A0",
      parent: "",
      subRows: [
        {
          code: "A01",
          parent: "A0",
          subRows: [
            {
              code: "A011",
              parent: "A01"
            }
          ]
        }
      ]
    },
    {
      code: "B0",
      parent: "",
      subRows: [
        {
          code: "B01", …
