Re: [Proto-Scripty] Prototype's selector as well as "eq" in Jquery

[Walter Lee Davis]

Sure. if you start at the tr that holds the tds, you can use down() to do this. If you want the second td to have a certain width, you could do this:

$$('tr').each(function(elm){
elm.down('td', 2).setStyle('width:122px');
});

You could probably also use

$$('td .yui-dt-liner div[id^=yui-gen]')[2].setStyle('width:122px');

for individual calls - but if you are going through multiple elements I would use each as Walter described

$("#table-id td:nth-child(2)")

will select 2nd cells in all rows of table with id "table-id"

[Jason Westbrook]

nth-child doesnt work in Internet Explorer CSS - can Prototype correctly decode that in IE?

Prototype does all the "CSS" stuff internally, and returns the correct element from the DOM. The browser doesn't have to do any heavy thinking.
