jQuery each loop in table row

I am having something like:

<table id="tblOne">
            <tbody>
                <tr>
                    <td>
                        <table id="tblTwo">
                            <tbody>
                                <tr>
                                    <td>
                                        Items
                                    </td>
                                </tr>
                                <tr>
                                    <td>
                                        Prod
                                    </td>
                                </tr>
                            </tbody>
                        </table>
                    </td>
                </tr>
                <tr>
                    <td>
                        Item 1
                    </td>
                </tr>
                <tr>
                    <td>
                        Item 2
                    </td>
                </tr>
            </tbody>
        </table>

I have written jQuery to loop through each tr like:

$('#tblOne tr').each(function() {...code...});

But problem is that it loops through the "tr" of "tblTwo" also which I don't want. Can anyone please suggest something to solve this?
