Thank you to everyone who have replied 
but ....
Sometimes this might be a long list, unalphabetized, and the words might be lb_nhb_5x_gihsd2_frnas, so spotting the differences between 2 columns is not practical. Yes, I have tried a lot of simple commands like paste, sort, uniq, and bdiff, but we would really prefer the following format for spotting the differences quicker and easier:
Desire Output:
File1 Files
-----------
die1
die2 die2
die3
lb_name1 lb_name1
lb_name2 lb_name2
lb_name3
Each of these columns is in a different file. I'm simply wanting to combine the 2 files, but have the same item in rows. The differences should be blanks. Even the paste -d \n command doesn't do this.
I've tried to type in the tabs between these 2 columns, but this forum will not let me use tab. With the tabs, it's really easy to spot the differences. I've been struggling with this problem for a week now. It's fun scripting but I've hit a wall, so I really need your help

fspec
fspec(4) File Formats fspec(4) NAME
fspec - format specification in text files DESCRIPTION
It is sometimes convenient to maintain text files on the system with non-standard tabs, (tabs that are not set at every eighth column). Such files must generally be converted to a standard format, frequently by replacing all tabs with the appropriate number of spaces, before they can be processed by system commands. A format specification occurring in the first line of a text file specifies how tabs are to be expanded in the remainder of the file. A format specification consists of a sequence of parameters separated by blanks and surrounded by the brackets <: and :>. Each parameter consists of a keyletter, possibly followed immediately by a value. The following parameters are recognized: ttabs The t parameter specifies the tab settings for the file. The value of tabs must be one of the following: o A list of column numbers separated by commas, indicating tabs set at the specified columns. o A '-' followed immediately by an integer n, indicating tabs at intervals of n columns. o A '-' followed by the name of a ``canned'' tab specification. Standard tabs are specified by t-8, or equivalently, t1,9,17,25, etc. The canned tabs that are recognized are defined by the tabs(1) command. ssize The s parameter specifies a maximum line size. The value of size must be an integer. Size checking is performed after tabs have been expanded, but before the margin is prepended. mmargin The m parameter specifies a number of spaces to be prepended to each line. The value of margin must be an integer. d The d parameter takes no value. Its presence indicates that the line containing the format specification is to be deleted from the converted file. e The e parameter takes no value. Its presence indicates that the current format is to prevail only until another format specifi- cation is encountered in the file. Default values, which are assumed for parameters not supplied, are t-8 and m0. If the s parameter is not specified, no size checking is performed. If the first line of a file does not contain a format specification, the above defaults are assumed for the entire file. The following is an example of a line containing a format specification: * <:t5,10,15 s72:> * If a format specification can be disguised as a comment, it is not necessary to code the d parameter.
