Question

I want to hide the rows from row index from 1 to 3. The below code is not working:

$("table").find("tr:gt(1)").find("tr:lt(3)").each(function () { $(this).hide() });

Answer 1

The first find() returns the matched elements and then the second one filters that selection further.

Try this selector

$('table tr:gt(0):lt(4)').hide();

Also, slice() would be a great option (if not the best)

$('table tr').slice(1,4).hide();
