Ignore Columns to export PDF

How i can ignore some column when i try to export grid data to PDF?
Example: i’ve five columns and in the 5 column only are an image and then i need ignore that column in the PDF report…

As far as I know, you are best to create a pdf report application based on the grid SQL and then delete the 5th column in the Layout section. In the grid app, add a button link and replace the std PDF link in the export group in the toolbar of the grid.

This gives your better control of the look and feel. However, I have not yet attempted to make a report that has group by’s with sub totals at each change.
