Help with Ruport

ruby-talk
1

Im very new to Ruby, and I am trying to reduce input from a ruport
report that I have generated. When I use the standard code to generate
the report, it works fine. But after trying to remove some of the
information on the report, I am running into errors. Here is a snippet
of the code:

[code]

require 'rubygems'
require 'ruport'

data = `df -h`.split "\n"
header=data.shift.split " ", 6
data = data.map{|line| line.split(/ +/)}
report = Ruport::Data::Table.new :data => data, :column_names => header
table = table.sub_table{("Filesystem , Size, Used")}
puts report

[/code]

If I remove the "table = table.sub_table{("Filesystem, Size, Used")}"
line it works great, but those three elements are the only portions I
want the report to generate.

Any help would be appreciated.

I am running into errors = I am getting "undefined method 'sub_table'
for nil:NilClass(NoMethodError)"

The reason this is confusing is because without that line, the code
works perfectly. I am still learning Ruby, so I am not sure if this
requires me to entirely rethink and recode what I am trying to
accomplish, or if there is something simple that I am missing. I got
that line of code from the ruport documentation, and implemented it the
way the documentation states. (at least to my understanding)

My apologies on the vague question before.

table = table.sub_table{("Filesystem , Size, Used")}

should this ^ be report? There is no table defined other than on this line
