% COMPLEXT.TEX - A sample AASTeX table with complex column headings. 

% This complex but short example of the deluxetable environment, using 
% either the apjpt or aj_pt style file, demonstrates some of the techniques
% that can be used to generate complex column headings and to align
% variable-width columns.

% In this example the LaTeX \multicolumn command is used to span a heading
% over several columns.  When \multicolumn is used along with the 
% \cutinhead command the \tablecolumns command must be used to specify
% the number of columns in the table - otherwise the \cutinhead command
% will not work properly.

% Note the use of the LaTeX command \cline and the use of a blank column
% between the two \cline commands needed to separate the horizontal lines
% generated by them.

% This table also makes use of the \phn command to better align some of the 
% columns.  Also see \phd, \phs, and \phm{} - other commands useful for column 
% alignment.  All of these commands insert a blank space equivalent to a 
% number (\phn), a decimal point (\phd), a minus sign (\phs), or any character
% you wish to use (\phm{text}).
