[Moo] Sortable Tabel ba date

[hamburger]

Hello,
i have a problem with my table i would like to sort by date.
my first collum is a date like  31. Januar 2011 - 23:29:07
but it sorts it by 31 not by date.
the docs says that it will be sorted by date and it mentiones
something by parsers what i do not understand.

my code:

var myTable = new HtmlTable($('theTable'),
        {sortable: true,
         zebra: true,
         classZebra: "zebra",
         classHeadSort:"downArrow",
         classHeadSortRev :"upArrow",
         classCellSort:"focusedColumn",
         });

where or how can i add the parser here?
thanks for help in advance
