DataTable: PT Options missing for Expansion Row Cell

[kaipaysen]

Describe the bug

The td Element surrounding the expansion template is not accessible with the PassThrough API.
I guess that is related to
https://github.com/primefaces/primevue/blob/master/components/lib/datatable/TableBody.vue#L94-L96.

Expected behavior

I'd expect a red bottom border for the expanded row.

There is a misunderstanding here. td already has a pt. But expansion is a slot and it totally depends on how the user will use it. We can only export data and index. It may not be right for us to intervene from the outside, because we may not be able to guess correctly how the user plans templating.

@tugcekucukoglu please have a look at the following screenshots

1. the td in the expansion row has no pc-section attribute.
   

2. compared to the td in body row which has a pc-section attribute.
   

I'd like to work on the DOM Element td outside of the slot.

Thanks for the screenshots. Is there any reproducer link for the issue?

I used the example you mentioned from then website to create the screenshots.
If you expand the first row a second tr will be visible which holds the "to-be-pted" td.
