The Columns property returns a single Column object or a Columns collection for this table view. Read-only.
Set objColumns = objTableView.Columns
Set objColumn = objTableView.Columns(index)
Object (Column or Columns collection)
If a Column object is to be accessed with the index parameter, the value of index must be between 1 and the size of the TableView object's Columns collection. This size is available in the collection's Count property.
Although the Columns property itself is read-only, the collection it returns can be accessed in the normal manner through its Add method, and the properties on its member Column objects retain their respective read/write or read-only accessibility.
