 * @class   vtkTableReader
 * @brief   read vtkTable data file
 *
 * vtkTableReader is a source object that reads ASCII or binary
 * vtkTable data files in vtk format. (see text for format details).
 * The output of this reader is a single vtkTable data object.
 * The superclass of this class, vtkDataReader, provides many methods for
 * controlling the reading of the data file, see vtkDataReader for more
 * information.
 * @warning
 * Binary files written on one system may not be readable on other systems.
