Reports - When exported to PDF

When a report with groups columns exported to PDF, PDF doesn't show the report with grouped columns. It just shows a list of rows. How do I get the report what it displayed in the PDF? Don't want screen grab like solutions.

Exported PDF:

As you can see Project Manager, Project Name and Project Health columns (Grouped) were lost.

Please suggest any solution that gives me "What you see is What you Get".

Thanks in advance.
