Adding animation via jquery
<p>I have the following Jquery code that insert a html after a specific <code>&lt;TR&gt;</code></p>

<pre><code>$("#imgDiminui_" + Id).closest("tr").after(row);
</code></pre>

<p>Works fine, but I would like to add a animation to this.</p>

<p>I try the following </p>

<pre><code>$("#imgDiminui_" + Id).closest("tr").after(row).animate({
                      height: "18px",
                      opacity: 0.25
                  , 500); 
</code></pre>

<p>Works fine,</p>

<p>But when I try </p>

<pre><code>$("#imgDiminui_" + Id).closest("tr").after(row).slideDown(1000);
</code></pre>

<p>Nothing happened. Somebody can help me to put the <code>slideDown effect</code> ?</p>
