Google Spreadsheet: Delete submission on integrated sheet as soon as it's deleted in JotForm.

when you delete an entry directly in the Jotform page where you have the entry list, how can that "Deletion" be updated in the Integrated Spreadsheet without breaking the integration.

Unfortunately, the integrated sheet will not be updated when you delete a submission on the JotForm website. 

I will open a feature request for this, although we cannot provide an ETA, we  will let you know as soon as we get any update about it.
