How to attach note/comment to a particular cell in Ruby Spreadsheet?

[rajanmodi]

Spreadsheet.client_encoding = 'UTF-8'
book = Spreadsheet::Workbook.new
sheet = book.create_worksheet(:name => "Test")
sheet.row(0)[0] = "Rajan" # putting value in 0th row and 0th column
comment = Spreadsheet::Note.new #Creating Note object
comment.objID = 0 . #Initialising instance variables of Note class
comment.row = 0
comment.col =0
comment.text = "Some Comment"
