BigBlueButtonBN provides an option for showing recordings in Plain HTML (default) or in a YUI datatable. The second one is for giving users the ability to, order columns and paginate the recording list when it has grown too long. But that UI has not been localised.
The problem is that the localisation has to be done trough the YUI plugin.
