ui grid expandable不显示数据

Question

我正在尝试在可扩展选项中绑定ui-grid。我能够获得数据但似乎具有约束力，我错过了一些东西。请有人建议

这是我的代码

- 控制器 -

            [{
                "Check_number": "116511",
                "Check_date": "2012-11-21T00:00:00",
                "Detail": [{
                    "Check_number": "116511",
                    "Voucher_number": "10000115",
                    "Invoice_number": "10000115",
                    "Invoice_date": "2017-03-23T16:03:38.303",
                    "Invoice_amount": 125.0,
                    "Vendor_number": "01234"    
                }, {
                    "Check_number": "116511",
                    "Voucher_number": "10000115",
                    "Invoice_number": "10000115",
                    "Invoice_date": "2017-03-23T16:03:38.303",
                    "Invoice_amount": 125.0,
                    "Vendor_number": "01234"        
                }]
            }]
