注释
If TRUE, the BeginAlter method has been used to mark the start of a unit of change for the Tableobject. The DoAlter method commits any changes made within the unit. The CancelAlter method rolls back any changes made.
If FALSE, no change unit exists. Changes made to the Table object properties, methods that affect the referenced Microsoft SQL Server table, and modification to the Table object collections cause immediate update requests to the instance of SQL Server.
