Go to the ms sql server database instance that has the table object and open a new query window. Execute the system stored proc called sp_changeobjectowner. The 2 parameters it needs to run are: (1) the current owner+object name and (2) the target owner. Take a look at the example below:
exec sp_changeobjectowner 'METRO\paula.EmployeeContact', 'dbo'
When the stored proc is completed, refresh the instance. The table will then be owned by dbo. In this example, the table would display as dbo.EmployeeContact
