removing last 3 rows of a table
<p>i have a table and i have two buttons to add and remove rows to this table .</p>

<p>so adding row is easy (i get 3 rows via ajax every time) .</p>

<p>now i want to be able to remove last 3 rows of table by clicking on remove button 
so unless there is some kind of function or .... to remove recent additions to my table ! i need to remove last three rows of table myself </p>

<p>something like </p>

<pre><code>$('#tbl tr:lt(3)').remove();
</code></pre>

<p>but last 3 not first ones ! </p>

<p>or i have to do something stupid like</p>

<pre><code>function remove(){
var i ;
for(i=0 ; i &lt; 3 ; i++ ){
$('#table tr:last').remove();
}
alert('removed');
}
</code></pre>

<p>bytheway i just wrote this last piece of code cuz apparently unless there is bunch of cods in my post It does not meet site quality standards !! </p>
