GetList()中根据实际情况请求后端获取数据

如果想处理res返回的结果，这里是在res中把No的值赋值给新增的Extra：

const GetList = () => {
    proxy.$axios.LoadClass("TrackerBom", " order by ID", 0).then(res => {
        res.forEach(svalue => {
            svalue['Extra'] = svalue['No'];
        })
        tableData.value = res;  
    })
}

如果在res中又嵌套了res，使用如下可以合并两个res的返回值：

const GetList = () => {
    proxy.$axios.LoadClass("TrackerBom", " order by ID offset 10 rows fetch next 5 rows only", 0).then(res => {
        proxy.$axios.LoadClass("TrackerBom", " order by ID offset 20 rows fetch next 5 rows only", 0).then(res1 => {
            res1.forEach((item) => {
                res.push(item);
            });
            tableData.value=res;
        })
    })
}
