Would like to work on this if no one else is. @iammarkps

No update since February. So, I would like to work on it now. @iammarkps @evexoio

I can't confirm if anyone is still working on this, so I think you can start if you want @thisisabhinay 👍

This one is difficult. I don't think the solution to this problem is 'only CSS' based. One way to solution is setting border-collapse property of the .is-bordered table to collapsible but then it defeats our whole purpose of setting the corner of table (in fact any bordered container) like this:

Part of the problem stems from the way of working of CSS itself! There's no 'pure CSS' way to change the properties of a parent based on the detection of one specific attribute (here, rowspan) in any of its children. CSS doesn't work like that, if I am not wrong.
