How to right-click on a SQL server table to directly change column properties?

I encountered some problems in SQL Server. I need to add fields to the table and modify the type of a field. Right-click the table and select Design to modify the fields. But at this time, you will encounter a problem, that is, the reminder below will not allow you to modify, so you will fail to modify

What to do? Click "Tools" - "Options" - "Designer" - remove the check mark before "Save changes that require table re-creation".
