/**
 * @class   vtkSparseArrayToTable
 * @brief   Converts a sparse array to a vtkTable.
 *
 *
 * Converts any sparse array to a vtkTable containing one row for each value
 * stored in the array.  The table will contain one column of coordinates for each
 * dimension in the source array, plus one column of array values.  A common use-case
 * for vtkSparseArrayToTable would be converting a sparse array into a table
 * suitable for use as an input to vtkTableToGraph.
 *
 * The coordinate columns in the output table will be named using the dimension labels
 * from the source array,  The value column name can be explicitly set using
 * SetValueColumn().
 *
 * @par Thanks:
 * Developed by Timothy M. Shead (tshead@sandia.gov) at Sandia National Laboratories.
