jQuery delete all table rows except first

Using jQuery, how do I delete all rows in a table except the first? This is my first attempt at using index selectors. If I understand the examples correctly, the following should work:

$(some table selector).remove("tr:gt(0)");

which I would read as "Wrap some table in a jQuery object, then remove all 'tr' elements (rows) where the element index of such rows is greater than zero". In reality, it executes without generating an error, but doesn't remove any rows from the table.

What am I missing, and how do I fix this? Of course, I could use straight javascript, but I'm having so much fun with jQuery that I'd like to solve this using jQuery.

Another way to accomplish this is using the empty() function of jQuery with the thead and tbody elements in your table.

Example of a table:

<table id="tableId">
<thead>
    <tr><th>Col1</th><th>Col2</th></tr>
</thead>
<tbody>
    <tr><td>some</td><td>content</td></tr>
    <tr><td>to be</td><td>removed</td></tr>
</tbody>
</table>

And the jQuery command:

$("#tableId > tbody").empty();

This will remove every rows contained in the tbody element of your table and keep the thead element where your header should be. It can be useful when you want to refresh only the content of a table.
