Event name: Quickbase training (text field)
Start date: 1 April 2020 (date field)
End date: 3 April 2020 (date field)
Duration (days): 3 (Formula - Numeric)

I want to create a new table that consists of attendees status dynamically based on the duration field above

Something like this if possible

If the Duration (days): 5, there will be 

Day 1
