iview table defaults to accepting only non-nested array objects in the following format
       data: [{
                    name: "John Brown",
                    age: 18,
                    address: "New York No. 1 Lake Park",
                    date: "2016-10-03"
                },
                {
                    name: "Jim Green",
                    age: 24,
                    address: "London No. 1 Lake Park",
                    date: "2016-10-01"
                }
            ]
but the data now returned by the backend is a nested array object, similar to the following:
        data: [{value: "jiangsu",
                label: "",
                children: [
                    {
                        value: "nanjing",
                        label: "",
                        children: [
                            {
                                value: "fuzimiao",
                                label: "",
                            }
                        ]
                    }
                ]is there a way for table to accept data in this nested format? Or is there any way to process data in this nested format into a format acceptable to table?
