I just made a small tweak to one of the lessons that adds info on  
targeting columns:

I assume the current column is the one being edited. In a column  
behavior you can access the dgColumn property to get the name of the  
column. This following lesson has an example.

How Can I Store An Option Menu Value When The User Makes a Selection?:

And I added an entry for dgColumn to the template custom props lesson.

There is also the dgColumnLabel[COLUMN_NAME] custom property that  
returns the label. It is discussed here:

The record number will be the line number.

The first lesson I pointed you shows how to use dgDataOfIndex/Line and  
GetDataOfIndex/Line. dgDataOfIndex gives you the whole row so your  
column will be included. GetDataOfIndex just returns a particular  
column. Both allow targeting of a specific line.
