Using the node import module, along with node update, I can upload a csv file and Drupal will generate a table complete with the proper css classes and id.
I am trying to understand how this actually works.
I've been looking through all the files in the module folder but I've yet to find how the proper css classes are applied to the generated html. If the module were just generating an html table, it would make sense, but somewhere, somehow a script is entering certain specific css classes to some rows, some cells etc.
Can anyone tell me were to focus /what files to look at for these types of configurations? Somebody here had to enter the actual classes somewhere in some script so that in the pipeline of generating the html table was instructed how to build the html table itself and when/where to add the css?
UPDATE: in case anybody else needs this, it seems most of this is in the node_import.admin.inc
