Here is a first take at it. It requires that you select the rows you  
want to work on. Let me know if it works consistently in this case.  
Input to selected text, output to replace selection.

#!/usr/bin/env ruby
require 'pp'
lines = STDIN.readlines.map {|line| line.chomp.split(/\s*&\s*/)}
table_lines = lines.reject{|line| line.length == 1}
columns = table_lines.shift.zip(*table_lines)
columns_lengths = columns.map{|column| column.map{|i| i.length}.max}
pattern = columns_lengths.map{|i| "%-#{i}s"}.join(" & ") + "\n"
for line in lines do
   if line.length == 1 then
     puts line
   else
     printf(pattern,*line)
   end
end
