I might be off base as to what you're really looking for, but since, I have gotten help here before, and I use crosstabs extensiviely, I might be able to help.
What do you mean by "Pertain to" is it just a description or does it provide a function?
It might be as simple as cntrl-right-clicking on the fields in the "New Column" and doing a Format object...Common...Suppress. In a crosstab, you can suppress a column. (Makes sure to get the title too.) If this was what you were trying to accomplish.
You might also want to Right Click the Crosstab object and try exploring the Crosstab Expert. Under customized style, there are tons of options. The showlabels checkbox saved me days of work once. (It shows the Name of the Column from the database. So, for instance, in your case it might show Quantity and Price if those are the names of the columns.)
Hope this might help. I am mostly familiar with Crystal Reports 2008 in a ASP setting.
Good Luck.
