Transposed (Vertical)Table

Problem/Motivation

I have a use case where I need a transposed (flipped/vertical) table. The current module functionality only supports horizontal tables and not vertical tables.

Steps to reproduce

Setup a data export view.
Look at view options for flipped / vertical table.

Proposed resolution

Attached is a patch file which I'm currently using for my use case.

Remaining tasks

Please review my work and let me know if there are improvements that can be made. I'm open to feedback.

User interface changes

I did add some GUI options to the PDF settings to that you can select a transposed table, enable a table header and set the labels for that header.

API changes

None

Data model changes

None.
