  /**
   * @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.
