tbody . each( ) ; method missing watir -

Hello there I'm not sure if I'm using wrong water syntax or if there is something wrong with my water Writing to go through each row of a table, the code below (

  e () {| I .....}   
 When I run this code, I get the wrong error code. Also, when I  
 e.frame (: name = & Gt; "content") frame (: name = & gt; "main")). ("Class =" gt; blacklabel "); Length ()  
 I get the missing method error below is the website I am using.  
   You want to repeat on the collection of rows rather than table - that is, you need to call  Rows ()  before  each () . You want to do this:  
  my_table = e.frame (: name = & Gt; "content") frame (: name = & gt; "main"). Tbody (: class = & gt; "B Laclabel ") my_table.rows.each {| i | .....}   
 TDE element uses tableshopping class. TableSection API can be seen here.
