Hi.

The best automatic alignment tool I've found is the perl script align. Here's a demonstration:

#!/usr/bin/env bash

# @(#) s1	Demonstrate automatic alignment, align.
# http://freecode.com/projects/align

# Utility functions: print-as-echo, print-line-with-visual-space, debug.
# export PATH="/usr/local/bin:/usr/bin:/bin"
pe() { for _i;do printf "%s" "$_i";done; printf "\n"; }
pl() { pe;pe "-----" ;pe "$*"; }
db() { ( printf " db, ";for _i;do printf "%s" "$_i";done;printf "\n" ) >&2 ; }
db() { : ; }
C=$HOME/bin/context && [ -f $C ] && $C align

FILE=${1-data1}

pl " Input data file $FILE:"
cat $FILE

pl " Results:"
align $FILE

exit 0

producing:

% ./s1

Environment: LC_ALL = C, LANG = C
(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.26-2-amd64, x86_64
Distribution        : Debian GNU/Linux 5.0.8 (lenny) 
GNU bash 3.2.39
align 1.7.0

Name1            Balaji                 NandaKishore

You could use expand (it usually works with TAB separated input so I used sed to convert your spaces to tabs first):

$ sed 's/  */\t/g' infile | expand -t 12
 
Name        FirstName   Lastname
------      ---------   ----------
Name1       Balaji      NandaKishore            
Name123     Vijaya      krsihna

Replace the 12 with any number you like for the column widths or specify tabstops as a comma list eg -t 12,18,35
