FTAB_PRINT

       Print the contents of a FITS (binary or ASCII) table extension.

       User can specify which rows or columns to print

       FTAB_PRINT, filename, columns, rows, [ TEXTOUT=, FMT=, EXTEN_NO=]

       filename - scalar string giving name of a FITS file containing a
               binary or ASCII table
       columns - string giving column names, or vector giving
               column numbers (beginning with 1).  If string
               supplied then column names should be separated by comma's.
       rows - (optional) vector of row numbers to print (beginning with 0).
               If not supplied or set to scalar, -1, then all rows
               are printed.

       EXTEN_NO - Extension number to read.   If not set, then the first
               extension is printed (EXTEN_NO=1)
       TEXTOUT - scalar number (0-7) or string (file name) determining
               output device (see TEXTOPEN).  Default is TEXTOUT=1, output
               to the user's terminal
       FMT = Format string for print display (binary tables only).   If not
               supplied, then any formats in the TDISP keyword fields will be
               used, otherwise IDL default formats.    For ASCII tables, the
               format used is always as stored in the FITS table.

       Print all rows of the first 5 columns of the first extension of the
       file 'wfpc.fits'
               IDL> ftab_print,'wfpc.fits',indgen(5)+1

       Uses the non-standard system variables !TEXTOUT and !TEXTUNIT
       which must be defined (e.g. with ASTROLIB) prior to compilation.
