Tablesorter is working fine, but all th elements are displayed in a column one under another instead of normal way of displaying in a row. Only IE display them right 
Here's the link: http://admiral.manfree.kiev.ua/ALFA-ROMEOWhen I remove tablesorter script, table is displayed correct. I have no additional classes on tables except tablesorter demo blue theme. My table head part is simple:\[code\]<table id='catalog_model_line' width='100%' class='tablesorter'> <thead> <tr> <th class="header headerSortDown">
