# "a=            340"
# "abc=          340"
# "acbfdhdfdf=   340"

some ways,

ar
#=> ["a= 340", "abc= 340", "acbfdhdfdf= 340"]

fixw
#=> 15

ar.each {|x| puts "%-#{fixw}s%d" % x.split}
a=             340
abc=           340
acbfdhdfdf=    340

puts ar.map {|x| "%-#{fixw}s%d" % x.split}
a=             340
abc=           340
acbfdhdfdf=    340

ar.each {|x| puts x.split.map{|y| y.ljust(fixw)}.join }
a=             340
abc=           340
acbfdhdfdf=    340

puts ar.map {|x| x.split.map{|y| y.ljust(fixw)}.join }
a=             340
abc=           340
acbfdhdfdf=    340
