Table snippet that works great across desktop/web/mobile incl. Outlook for Windows:
Adding white-space: nowrap; preserves that the text doesn't wrap in the table cell if the table width is above 320px which is the limit for Mobile-Ready designs.
<table border="0" cellspacing="0" cellpadding="0" style="border:none; mso-table-lspace:0px; mso-table-rspace:0px; mso-cellspacing: 0px; mso-padding-alt: 0px 0px 0px 0px; border-collapse:collapse; width: 320px;"> <tr> <td width="320" height="13" style="width: 320px;height: 13px; white-space: nowrap;"> <font face="Arial, Helvetica, Sans-Serif" color="#000000" style="FONT-SIZE: 13px"> </font> </td> </tr> </table>
