This node populates a new column (appended to the input DataTable) by executing the specified JPython function once per row in the input DataTable. The values for each column in the input row may be accessed via the val("column name") (returning float, int or string) or the valplain("column name") (returning the concrete cell object) JPython function. For example, a simple JPython function to sum the values in 2 input columns might be:
val("col1") + val("col2")
Currently employs jython v2.2.1.
