2. Switch to design view by right-clicking on the table name and selecting “Design View.”
3. Locate the field for which you want to change the default value property.
4. In the “Default Value” property box for that field, enter the new default value that you want to set.
5. Save the changes to the table by clicking on the save icon or pressing Ctrl + S.
6. Close the design view and return to the table view to see the changes reflected.
