[jQuery] How do I select this td?


How would I select the first td in this table?
I tried:
$("#sortable-tbl tr td:first")
but that didn't work...
                                
    <table id="sortable-tbl">
    
        <tr id="2">
            <td id="7">New Community Section 1 Title</td>
            <td><a href="community_section_update.cfm?section_id=7">Update</a></td>
            <td><a href="community_section_delete.cfm?section_id=7">Delete</a></td>
        </tr>
                            
        <tr id="3">
            <td id="1">Community Section Title 1</td>
            <td><a href="community_section_update.cfm?section_id=1">Update</a></td>
            <td><a href="community_section_delete.cfm?section_id=1">Delete</a></td>
        </tr>
                                
        <tr id="4">
            <td id="2">Community Section Title 2</td>
            <td><a href="community_section_update.cfm?section_id=2">Update</a></td>
            <td><a href="community_section_delete.cfm?section_id=2">Delete</a></td>
        </tr>
