    // add columns
    customerTable.Columns.Add( "id", typeof(int));
    customerTable.Columns.Add( "name", typeof(string));

    // set PrimaryKey
    customerTable.Columns[ "id" ].Unique = true;
    customerTable.PrimaryKey = new DataColumn[] 
        { customerTable.Columns["id"] };

    // add a RowDeleting event handler for the table.
