Just started a new version of My Demo Application - based on APEX 5.0 and Universal Theme. There, I will rework the old content and provide some interesting new possibilities (as of 4.2). In this example I am showing how to change the column type from Text to Display in a tabular form.
When could this be useful? For example if you have a certain group of users not allowed to edit a column and you don't want to create additional and conditional columns. Eventually you can use this to set only specific rows to display only depending on your application logic.
