javascript - 数组替换而不是连接值

Question

我将此数组声明为

rowData = []

我想用 forloop 更新这个数组，但它不断替换值而不是更新它。我想我做错了什么。

    rowDataDefs(){
        for (let to of this.detailedOrders){
            console.debug(to)
            this.rowData = [
                {table_no: to.table.tableNo, order_no: to.orderNo, date_time: to.table.createdDate }
            ]
        }
    }

rowDataDefs(){
        for (let to of this.detailedOrders){
            console.debug(to)
            this.rowData.push(
                {table_no: to.table.tableNo, order_no: to.orderNo, date_time: to.table.createdDate });
        }
    }
