footSum으로 계산된 값을 사용하고 싶은데 어떻게 해야 하나요?
footSum: [[
{label: “”, align: “center”},
{key: “chargeAmt”, collector: “sum”, formatter: “money”, align: “right”},
{key: “paymentAmt”, collector: “sum”, formatter: “money”, align: “right”},
{key: “balanceAmt”, collector: “sum”, formatter: “money”, align: “right”},
]],`
