Subject: Re: Building tables dynamically with CGI class

Thanks for your help Jim.  The following code does exactly what I want:


#!/usr/bin/ruby

require 'cgi'

cgi = CGI.new("html4Tr")

table = [
    ['00', '01', '02', '03'],
    ['10', '11', '12', '13'],
    ['20', '21', '22', '22'],
    ['30', '31', '32', '33']
]

cgi.out{
  cgi.body{
    cgi.table{
      cgi.tr{cgi.th{"One"} +
             cgi.th{"Two"} + 
             cgi.th{"Three"} +
             cgi.th{"Four"}} +
        table.collect{|row|
          cgi.tr{  
          row.collect{|item|
            cgi.td{ item }
          }.join
        }
      }.join
    }
  }
}
