内部 table 中的最后一行不会在固定数据 Table 中展开

Last rows in inner table don't expand in Fixed Data Table

我在 fixed-data-table-2 组件中使用 expanded rows。我在内部 tables:

上有 3 个级别

如果我单击内部 table(第二个嵌套级别)中的折叠单元格,行不会展开,最后一个嵌套 table 也不会呈现。它在第一次单击父行后发生,但在第二次单击后呈现 table。

更奇怪的是,如果 a) 我点击第二行的前三行 table 或 b) 如果我展开 main(first) 中的第一行 table

如果主 table 的第一行以外的其他行被扩展,则第二行 table 的最后一行会发生这种情况。

您可以在 this and this 记录中看到此行为。

我应该发表评论,但我没有要求的否。的点数。你解决了这个问题吗?因为我刚刚打开了你附加的 link 并且它工作正常

更新 您的代码工作正常。您的方法的问题是您的点击事件是在箭头上触发的,而不是在整个 div (或单元格)上触发的。因此,您需要切中要点,只需单击箭头即可展开您的行。如果您不希望出现这种情况,我建议您将点击事件放在 div(或单元格)

这是一个工作视频,证明它工作正常: https://www.useloom.com/share/2c725f3fede942b09c661a765c72634e

我从您的视频中截取了一张屏幕截图,显示由于您没有点击箭头,所以您的行没有展开

我已经更新了沙盒代码,请查看下面的内容link,我认为它对你有用
