新版表单自定义实体主子明细，子表单合计行

//在金额(amount)产生变化时，计算并更新总价
const subEntityTable = new xsyrpa.FormSubEntityTableExtensionPoint("xsy.breeze.web.quote.quoteLine.defaultBusiType.childEntityCreation.ec");

subEntityTable.on("onChange", (data) => {
    console.log(data);
    const sum = data.reduce((pre, curr) => {
        return (curr.amount || 0) + pre;
    }, 0);
    subEntityTable.setFooterText({
        text: "销售金额总价（元）： " + sum 
    });
});

//注意：javascript有精度问题，最好将计算结果精确到几位小数
//sum.toFixed(2)
