That rendering method should not use cell style attribute at all.
Instead, the alignment should be controlled by CSS. However, this will
require more massive changes in the Lesson code to be done by the module
maintainer. As a temporary fix, left alignment is set as it usually
matches the layout that students see.
* class html_component does not exist any more
* class html_table rendered via html_writer::table()
* html_table, html_table_row and html_table_cell have public $attributes property to set their CSS classes
* dropped rotateheaders feature, should be added again after more research of possible ways (<svg> is not nice IMHO)
* dropped possibility to define CSS classes for table heading, body and footer - can be easily done and better done using just table class and context
The following are notable changes made in this commit
* Lesson page type are now class based and extend an abstract class. This includes a class for the page type and a class for the creating/editing a instance of this page.
* Converted all forms to mforms
* Action script located in mod/action/* were worked into the above so far less switch statements and the action directory will be removed.
* Implements a custom renderer
* Converted everything to use page, output, and custom renderer methods
* Replaced all deprecated methods incl. print_textarea conversions
* Tried to cut down on excessive DB calls.
Things worth noting:
* The focus of this patch was on cleaning up the module not rewriting it, as such I have organized NOT rewritten. There are still many areas in the module where the code could be greatly improved however to do so would require a rethink/rewrite
