js 将数组中某个字段相同的合并为一组（续）

现在将custId相同的合并为一组（同时将其保存在嵌套表格中），所以需要的数据格式为下图的额格式

具体代码：

//嵌套表格：
<a-tabs type="card" v-model="defaultActiveKeyGc">
                <a-tab-pane :tab="item.name" v-for=" (item,index) in checkedList" :key="item.custId">
                  <a-table
                    :columns="columnsGcReq"
                    :data-source="item.order"
                    class="components-table-demo-nested"
                    :rowKey="(record)=>record.infoId"
                    :expandedRowKeys="expandedRowKeys"
                    :loading="tableLoading"
                    @expand="expand"
                  >
                    <div slot="expandedRowRender" slot-scope="record" style="margin: 0">

<!--                      {{item}}-->
<!--                      {{record}}-->
<!--                      {{item[record.no]}}-->
                      <a-table
                        slot="expandedRowRender"
                        :columns="innerColumnsGcReq"
                        :data-source="item[record.no]"
                        :rowKey="(records)=>records.infoId"
                        :pagination="false"
