To prohibit certain users from deleting rows or restrict them to certain spreadsheets, you can set up permissions in the Excel spreadsheet. Here are the steps you need to perform:

1. open the Excel spreadsheet in Microsoft Teams.
2. click the "File" tab at the top of the Excel toolbar.
3. select "Share" from the menu on the left.
4. select "Invite People" from the drop-down menu.
5. enter the email address of the user you want to grant access to.
