I've created a custom report. The report has a significant number of fields in it which are required for when it's exported in CSV form.
What I'm trying to figure out is if there's a way to omit the rendering of some of the fields on the front-end grid. Most of them aren't really important for the filtering process in admin and are only used when the report is downloaded for further parsing outside of Magento.
I would expect this to type of functionality to reside in the grid class as that's what generates the actual grid and, later on, the exported CSV but I don't see anything that looks like it deals with visibility.
Before I go in and override methods in this class for our custom report, is there a lesser-known way to accomplish this that's easier than my adding some kind of "showInGrid" property via the addColumn property array?
TL,DR is there an easy way to have fields exported (in say, CSV or XML) but omitted from the admin grid?
