Table表格组件 树形结构数据懒加载 load只会执行一次

需求背景：当前树形节点已展开，用户操作修改数据，更新视图；

实现逻辑：巧用ES6 Map

data:{
	refreshTableTree： new Map()
}

		async handleLoad(tree, treeNode, resolve, isManual = true) {
            if (isManual) {
                this.tableTreeRefreshTool.set(tree.Id, { tree, treeNode, resolve });
                this.parentRegionIds.push({
                    id: tree.Id,
                    parentId: tree.ParentId,
                    hasChildren: tree.hasChildren,
                });
            }
            let { value } = await this.$api.erpbill.GetCustomerSaleRegionByParentId(tree.Id);
            resolve(
                value.Rows.map((item) => {

                    };
                })
            );
        },
