I'm wondering if I add a comment to the each column? like description. 

I would like to add some description to each column title when users drag. I usually use a lot of abbreviation on the column title. I want users to easily know what does the column title means. 

I tried to find the way. However, I couldn't find it except for just adding a comment to the cell. 


Thank you.


What you are trying to do is not possible. You have to make the column title descriptive. Sorry.
