Expandable "Detail" Table Rows_jquery

A common UI is to have a table of data rows, which when clicked on expand to show a detailed breakdown of "child" rows below the "parent" row.

The only requirements are:

Put a class of "parent" on each parent row (tr)
Give each parent row (tr) an id
Give each child row a class of "child-ID" where ID is the id of the parent tr that it belongs to

Example Code
$(function() {
$('tr.parent')
.css("cursor","pointer")
.attr("title","Click to expand/collapse")
.click(function(){
$(this).siblings('.child-'+this.id).toggle();
});
$('tr[@class^=child-]').hide().children('td');
});Example Table (click a row)
