When doing a new CSV import, you can add records, modify existing ones, but you can’t delete records from your old table that aren’t in the new dataset.
It would be good to have this as an option, or at least highlight the records that are from a previous import which weren’t present in a new csv import.
I would also support this feature very much. My use case is a regular update I run from a salesforce report into airtable. Sometimes records are disqualified over time and so it would be good if I could remove these records from the airtable in an automated way. At the moment, there is a lot of effort involved as I need to recreate a table with all the different views every now and then. Implementing this feature would improve my usage of the CSV block quite a bit.
