Question

I have one table with some data. After some event I want to highlight column.

http://jsfiddle.net/bpGaf/

jQuery('#tableFilter td:eq(2)').each(function(){
    jQuery(this).css('background-color','#cc0');});

But It highlight only one cell even I have used each function.

Answer 1

Your selector says “Of all the <td> elements inside #tableFilter, consider only the 3rd one”, rather than “Take the 3rd <td> in each <tr> inside that table” as it should.

This would do what you want it to do:

jQuery('#tableFilter tr').each(function() {
    jQuery(this).find('td:eq(2)').css('background-color', '#cc0');
});​
