    Description

      Say beatles is a ProjectableFilterableTable, below Sqls fail to do column pruning by BindableTableScan

      Schema of beatles:
      i int
      j int
      k int
      
      
      select k, 3 from beatles;
      
      select k + j from beatles;

      The reason is that ProjectableFilterableTable only works when the Project is a simple mapping.
