    Description

      In order to support table value function windowing, EnumerableTableFunctionScan's implement() should have an implementation which generates code that iterates input, calls the RexCall and generates output (can refer to the implementation of EnumerableCalc).

      For example, assume the input of table function is:

      col1 timestamp, col2 int, col3 char

      enumerable table function scan should emit
      col1 timestamp, col2 int, col3 char, wstart timestamp, wend timestamp
