Unfortunately, we don't have the ability to recover deleted columns. Once a column is deleted, it would need to be re-created, and the data would need to be re-fetched from its providers. To delete a column in the future, you can click on the column you want to delete within your table, then select 'Delete' from the dropdown menu and confirm your changes. If you need help recovering credits or have any other concerns, please let us know more details so we can look into it with you. If you need further assistance, you can request human help by clicking on "Talk to a person".
