Jasper reports 如何在Jasper报告中创建重复父元素值的表

我需要使用Jasperstudio 6.2.12使用JSON数据创建一个表，并将其导出为.xlsx格式。我可以创建如下所示的表：

我的要求是根据E和F列中的行数迭代A、B、C和D列中的值。预期产出为：

我用来打印表的JSON数据是：

{
"root": [{
        "firstName": "John",
        "lastName": "Doe",
        "accounts": [{
            "bank": "LLOYDS",
            "accountNumber": 123456,
            "references": [{
                    "name": "Eva Doe",
                    "refAccountNumber": 6549873

                },
                {
                    "name": "Robin Doe",
                    "refAccountNumber": 3216545

                },
                {
                    "name": "Peter Doe",
                    "refAccountNumber": 9876549

                }
            ]

        }]
    },
    {
        "firstName": "James",
        "lastName": "Doe",
        "accounts": [{
            "bank": "HSBC",
            "accountNumber": 654321,
            "references": [{
                    "name": "Sam Doe",
                    "refAccountNumber": 6549873

                },
                {
                    "name": "Roger Doe",
                    "refAccountNumber": 3216545

                },
                {
                    "name": "Jason Doe",
                    "refAccountNumber": 9876549

                }
            ]

        }]
    }
]}
