How to hide/show Table Rows with jQuery

With jQuery, hiding and showing DOM elements are easy. But, one thing that I find a little bit challenging is hiding table row(s). Hiding and showing DIVs are easy:

function togglePanel(id) {
var viewContainer = $(id);
viewContainer.slideToggle("normal");
}

Or you can use show() and hide() or fadeIn() and fadeOut(). With our corresponding HTML:
<a href="javascript:togglePanel('#myDiv')">Toggle</a>
<div id="myDiv">Hello World</div>


Now what if we are using TABLE instead of DIV??

Easy - Use TBODY tag. Here is an example using TABLE:
<table id=anothersortable>
<tbody id=row01 class=content>
<tr><td>one</td></tr>
</tbody>
<tbody id=row02 class=content>
<tr><td>two</td></tr>
</tbody>
</table>
<a href="javascript:togglePanelMore('#row01', '#togglerow01')"      id="togglerow01">less</a> for row01

Then our jQuery to be as such:
function togglePanelMore(id, source) {
var viewContainer = $(id);

if ($(source).html() == "more") {
$(source).html("less");
viewContainer.show();
}
else {
$(source).html("more");
viewContainer.hide();
}
}

IE 7 Quirks
In IE 8, you can refer to the TR directly without TBODY, like this:
<table id=anothersortable>
<tr id=row01><td>one</td></tr>
<tr id=row01><td>two</td></tr>
</table>
<a href="javascript:togglePanelMore('#row01', '#togglerow01')"
id="togglerow01">less</a> for row01
But for some reason, it is not reliably working in IE7.

Also, in IE7, putting speed inside the hide()/show() into becoming like hide('slow') won't work.

Here is a small demo.

Doesn't work. ".hide()" object doesn't support this method...
