vtkTable parent class

vtkDataObject contains the methods SetFieldData and GetFieldData, which could be used to set or get the columns of the table. The columns may currently contain primitive data types and recently vtkStringArray has been added to VTK.

We could also consider inheriting from vtkDataSet, which contains mechanisms for assigning coordinates to each row of the table. These could be initialized to zero and modified when the table is graphically presented. However, vtkDataSet also has the concept of cells, but tables do not have this concept since all rows are independent of each other.

vtkTable should probably extend vtkDataObject, and then be converted to a subclass of vtkDataSet using a filter which determines coordinates for each row.
