Help with Ruport

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:


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

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.

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