To delete all rows in a table within SEI, you can follow these steps:

* Upload an Empty CSV: Upload an empty CSV file to the table where you want to delete all rows. This will essentially replace the existing data with no data.

Yes, you can quickly drop and recreate a table in SEI using the following steps:

* Save Changes: After uploading the empty CSV, save the changes to remove all rows from the table.
