Defining array index in a jQuery selector

I have several tables in my HTML markup which don't have any attributes and I'm wondering: is it possible to define a jQue开发者_如何学JAVAry selector which directly picks eg. the third table?

In addition to Tim's answer, there's a :eq() version you can use inside a selector as well, for example:

$("#myContainer table:eq(2) tr")

yeah you can use eq from jquery

$('table').eq(2).css('background-color', 'red'); for example this gets the third table (zero-based counting, jquery starts counting with zero therefor eq(2)) and give it a red background color.
