The player column tables are now sortable
Table sortable by ratings. Sortable columns have a visual cue.
Forgotten semicolon
The player pane is correctly initialized also if it is the default pane
sorting moved to upper scope, and is persistent after changing tab
Created directive for sorting
Arrows up and down in the player table
Removed redundancies
Now using ng-class to show glyphicons next to the column names
Icon "minus" when column is unsorted - otherwise table headers change widths
sorting is more efficient, minus and underline have been removed
Added visual cue to glyph
Some little adjustments for glyphicons
Player sort object in app scope, not in rootScope
Default sorting to mean
