热心网友来啦！感谢楼主的分享，这个功能真的很实用！

看了一下你的代码，思路非常清晰，用展开行+嵌套vxe-grid的方式实现父子表格效果很棒。给你点赞！👍

不过有几点小建议可以优化一下：

1. **关于子表格数据传递**：你这里直接用的是 `:data="row.childList"`，其实也可以用 `:records="row.childList"`，两种方式都可以。

2. **关于展开列的固定**：你设置了 `fixed: 'left'`，这个没问题，但如果表格出现横向滚动时，展开列会跟着滚动，这个设计是正确的。

3. **性能小提示**：如果数据量比较大，建议给子表格加上 `lazy` 懒加载功能，这样可以避免一次性渲染太多数据导致卡顿。

4. **样式方面**：子表格的 `expand-wrapper` 样式可以稍微丰富一点，比如加个背景色或者边框，看起来层次更分明。

总的来说这个方案非常不错，代码整洁易懂，对于需要展示层级数据的场景很实用！👍

再次感谢楼主的无私分享，已经收藏了！🎉
