Show/ Hide Table Column with colspan using jQuery

Question

I have a HTML table as shown in http://jsfiddle.net/Lijo/auny3/ . The table has 10 columns – divided into three col groups. I need to hide/show the colgroup named “Associate Info” (including its rows data) using buttons “Show Associate” and “Hide Associate”.

What is the best way (in terms of performance) for doing this using jQuery?

Please answer if you have a better answer than http://jsfiddle.net/Lijo/auny3/8/

Note: I am generating the table using ASP.Net GridView as given in http://www.sacdeveloper.com/Community/Articles/tabid/86/ctl/ArticleView/mid/458/articleId/1/Group_columns_in_an_ASPNet_Gridview.aspx

Or you can use nth-child selector:

$('input').click(function(){
    if($(this).val() == "Hide Associate"){
    $('th:nth-child(2), td:nth-child(2), th:nth-child(3):not(:first), td:nth-child(3), th:nth-child(4), td:nth-child(4), th:nth-child(5), td:nth-child(5)').hide();
    }else{
        $('th:nth-child(2), td:nth-child(2), th:nth-child(3):not(:first), td:nth-child(3), th:nth-child(4), td:nth-child(4), th:nth-child(5), td:nth-child(5)').show();
    }
});
