2个数据表在2个表之间切换可扩展行

Question

嘿，我需要在同一页面上使用两个数据表的一些帮助。我需要做的是当表1（T1）的行（R1）展开时，我需要R1在用户扩展表2（T2）的行（R2）时折叠。这是一个设置有2个数据表的codepen，它们随我的解决方案扩展：https://codepen.io/BrandiW/pen/WgLPej?editors=1010如您在该codepen中所见，我正在使用一个名为Expanded的变量来当前将v-card隐藏在扩展行中，被关闭，但是问题在于它实际上并没有关闭该行。因此，如果要备份打开此行，则必须双击它（一次将其关闭，另一次重新打开）。

示例问题：

• 工作：点击T1-R1，然后T2-R2，然后T1-R3
• 不起作用：依次单击T1-R1和T2-R2，然后选择T1-R1或T1-R2

代码（先是HTML，然后是Java脚本）：
