我不知道怎么循环出roles的数据。

    "demoData": [
        {
            "dp": "aaa1",
            "name": "用户名1",
            "number": "11111",
            "score": "22222",
            "salary": "11111",
            "jobs": "scripts",
            "roles": [
                {
                    "new": "bbb",
                    "edit": "ddd",
                    "ccc": "aaaa",
                    "del": "dddd"
                }
            ],
            "other": "备注",
            "action": "删除"
        },
        {
            "dp": "bbb",
            "name": "用户名1",
            "number": "11111",
