把两个数组按照其中一个数组的顺序 进行排序？

将oneArr 按照 twoArr 的顺序进行排序，而且两个数组可能一样长，也可能不一样长，
twoArr 是基于oneArr选中的数据，oneArr 是接口返回的数据，

oneArr = [
    {
        "intID": 4070479,
        "sourceTableMetaId": 225378,
        "strColumnNameEN": "id",
        "strColumnDescZHCN": "ID",
        "index": 0,
        "_index": 0
    },
    {
        "intID": 4070480,
        "sourceTableMetaId": 225378,
        "strColumnNameEN": "kpi_id",
        "strColumnDescZHCN": "",
        "index": 1,
        "_index": 1
    },
    {
        "intID": 4070481,
        "sourceTableMetaId": 225378,
