How to get columns definition from a renderer

I need to get the original column definition inside a custom renderer. What function do I need to call?
Also how can I define custom options to a column to be used in an editor or renderer.

TIA

Hi @pdemilly

Sorry for a late reply. I hope that you have already found an answer for your question but if not please share more details about your request.

If I understand you want to refer to any column via index to perform some actions inside custom renderer. If so, here’s http://jsfiddle.net/handsoncode/oh8nynqx/ a basic example when I color cells only in column 1.

ps. if you ask me better way to do it is by using cells options still I’ve added this example as it’s one of basic things that we can do with it.
