将每一层添加children:[]，并将orgName改名为label

Answer 1

arr[0] = arr[0].map(({orgName, ...v}) => ({...v, label: orgName, children: []}))
console.log(arr)

  let list = []
  for (let item of arr) {
    item = item.map(val => {
      val.label = val.orgName
      delete val.orgName
      return { ...val, children: [] }
    })
    list.push(item)
  }
