formatting on table cells lost when using jQuery

formatting on table cells lost when using jQuery

A table is hidden when the page loads.

When the user clicks on a checkbox the table will slide down.

When I don't use jQuery to manipulate the table there is spacing between the cells.

If I do use jQuery, then the spacing between the cells is lost, despite me not changing any class/id attributes.

There are two tables with the class ".formTable" on the page and it's the second one, hence my referring to it using '.formTable:eq(1)'.

The table doesn't have any IDs. This is the code I was trying to use:
      $('input[@name="inform_friends"]').click( function(){
         if (this.checked) {
            $('.formTable:eq(1)').slideDown('slow');
         }
         else {
            $('.formTable:eq(1)').slideUp('slow');
         }
      })


Hope you can help me. Many thanks, Gabe.
