有没有办法增加对树形数据结构场景的支持,或者在现有基础上支持树形结构的虚拟列表渲染

已经有基于vue-virtual-scroll-list的虚拟列表树实验案例，搜索虚拟列表树可以得到非常多，最简做法可以参考https://juejin.cn/post/7062676726307880997

最简做法支撑少量设备没有问题，但是对于大数据量支撑依旧存在较大的瓶颈，单个树节点下超5w+勾选就会卡顿，并且接口获取数据下载耗时也极长

目前有实践基于vue-virtual-scroll-list实现虚拟列表树，支撑每个树节点下20w+数据基本没有问题：

懒加载，解决树层级过多问题
游标分页，解决单级节点数据量过多问题

效果：

展开树节点，懒加载当前节点下的前100条
滚动到当前节点下最后一条数据时，再次触发本节点下一页请求
各个节点存储自己使用的分页参数及resolve
