I've built a template based on one of the provided templates and I'm having an issue where Outlook 2013 appears to be ignoring the cellpadding in a table which contains my logo.

Here's the code:

    <table width="640" cellspacing="0" cellpadding="0" bgcolor="#" class="100p">
                <tr>
                    <td background="images/header-bg.jpg" bgcolor="#3b464e" width="640" valign="top" class="100p">
                        <!--[if gte mso 9]>
                        <v:rect xmlns:v="urn:schemas-microsoft-com:vml" fill="true" stroke="false" style="width:640px;">
                            <v:fill type="tile" src="header-bg.jpg" color="#3b464e" />
                            <v:textbox style="mso-fit-shape-to-text:true" inset="0,0,0,0">
                                <![endif]-->
                                <div>
                                    <table width="640" border="0" cellspacing="0" cellpadding="20" class="100p">
                                        <tr>
                                            <td valign="top">
                                                <table border="0" cellspacing="0" cellpadding="0" width="600" class="100p">
                                                    <tr>

The logo renders justified all the way to the left of the header.

Thanks in advance for your help.
