Currently, Paperback does not support tables. Tables appear in many books, and adding support for them would make Paperback more suitable for educational environments.
For example, QRead supports tables. When a user reaches a table in QRead or presses T/ SHIFT+T, they can even press the Enter key, and the table is displayed in a wxWebView with full support for table navigation keys in screen readers. However, I am not sure whether rendering through wxWebView is even possible in Paperback, or how compatible such an approach would be with security principles.
