Pretty straightforward. Having the ability to use {{index}} would be awesome. Especially for row actions to move a row up or down. Same is possible by creating a field using one field but it just seems wasteful to create a field in order to expose this functionality.
IF({{Record.isFirst}}, “First”, IF({{Record.isLast}}, “Last”, “Middle”))
Slightly better UX for formula option.
I’m sure a use case for {{index}} has been wanted before as well.
