Adding/Removing MetaColumn from MetaTable

Question

I'd like to add/remove a column from MetaTable. But table.Column is of type ReadOnlycollection<MetaColumn>.
How can I modify, add or remove a column from the table?
Thank you.

Have you tried ScaffoldColumn?

[MetadataType(typeof(FooMetadata))]
[TableGroupName("Foo")]
    public partial class Foo 
{ 

        [ScaffoldColumn(true)]
        public string MyNewColumnNotinDBTable
        {
            get
            {
                return "FooBar";
            }
        }
}



 public class FooMetadata
    {
        [ScaffoldColumn(false)]     // hide Id column
        public object Id { get; set; }


        public object Name { get; set; }

        public object MyNewColumnNotinDBTable { get; set; }
    }
