// .NAME vtkTableFFT - FFT for table columns
//
// .SECTION Description
//
// vtkTableFFT performs the Fast Fourier Transform on the columns of a table.
// Internally, it shoves each column into an image data and then uses
// vtkImageFFT to perform the actual FFT.
//
// .SECTION See Also
//
// vtkImageFFT
