I've been trying to figure this out for a while but I'm completely stumped. I have files with data in rows and I need to convert the data to columns.

I want to lookup values from two different tables based on common columns and append. The trick is the column to be looked up is not fixed and varies , so it has to be detected from the header. How can I achieve this at once, for multiple data files, but lookup tables fixed.

pdl::graphics::lut
LUT(3pm) User Contributed Perl Documentation LUT(3pm)NAME
PDL::Graphics::LUT - provides access to a number of look-up tables
SYNOPSIS
use PDL::Graphics::PGPLOT;
use PDL::Graphics::LUT;
# what tables are available
my @tables = lut_names();
# get the reversed colour table 'smooth',
# with the gamma intensity ramp
my ( $l, $r, $g, $b ) = lut_data( 'smooth', 1, 'gamma' );
# use the table idl5 in ctab
ctab( lut_data('idl5') );
DESCRIPTION
PDL::Graphics::LUT contains a number of colour look-up tables (in rgb format) and intensity ramps, and provides routines to access this
data. The format of the data is suitable for use by ctab.
Unlike the initial release of the package, the data tables are now stored within the PDL distribution as FITS files (see $tabledir and
$rampdir), rather than in the module itself. Changes to these directories will be picked up on the next call to one of the package
functions.
FUNCTIONS
lut_names()
Return, as a list, the names of the available colour tables.
@tables = lut_names();
lut_ramps()
Return, as a list, the names of the available intensity ramps.
@ramps = lut_ramps();
lut_data()
Load in the requested colour table and intensity ramp.
( $l, $r, $g, $b ) = lut_data( $table, [ $reverse, [ $ramp ] ] );
Returns the levels and r, g, b components of the colour table $table. If $reverse is 1 (defaults to 0 if not supplied), then the r, g, and
b components are reversed before being returned. If not supplied, $ramp defaults to "ramp" (this is a linear intensity ramp).
The returned values are piddles containing values in the range 0 to 1 inclusive, and are floats.
VARIABLES
$tabledir
The directory in which the colour tables (in rgb format) are stored.
$rampdir
The directory in which the intensity ramps are stored.
$suffix
The suffix for the data files in $tabledir and $rampdir.
FURTHER INFORMATION
The colour tables were taken from the STARLINK GAIA package, and are provided under the GNU copyleft. See http://star-www.rl.ac.uk/ and
http://star-www.dur.ac.uk/~pdraper/ for more details.
