CVS tags:
HEAD
- Use LON-CAPA standard data tables in Construction Space and Portofolio Tables
- Moved color indicator from whole background to new and only small column.
This should prevent a "color shock" but keeps the "show status by different colors" functionality.
loncommon.pm:
- Adjusted the related styles ("LC_browser...") correspondingly to the changes described above.
Additional changes/optimizations/corrections in portfolio.pm:
- Added missing &mt() calls to headline in selection mode
- Replaced hardcoded nobreak with CSS
- Fill empty table cells in directory rows with blanks to have a proper table structure
- Optimized and extended colspan precalculation
- XHTML conform "checked" usage in checkboxes
