/**
* @class vtkTableToArray
* @brief converts a vtkTable to a matrix.
*
*
* Converts a vtkTable into a dense matrix. Use AddColumn() to
* designate one-to-many table columns that will become columns in the
* output matrix.a
*
* Using AddColumn() it is possible to duplicate / reorder columns in
* arbitrary ways.
*
* @warning
* Only produces vtkDenseArray<double>, regardless of the input table column types.
*
* @par Thanks:
* Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
