const productsTypeG = function (deptArray) {
    deptArray.forEach(el => {
        delete el.children
    })
    let map = {}
    deptArray.forEach(el => {
        map[el.id] = el//循环data拿到所有id
    })
    let arr = []
    deptArray.forEach(el => {
        let parent = map[el.fatherId]//拿到所有pid，如果为真，与id进行对比，如果pid===id，说明为id的子集
        if (parent) {
            (parent.children || (parent.children = [])).push(el)
        } else {
            arr.push(el)
