I created a responsive data table for an email campaign in Design Studio. For this to work, the table uses the data-title attribute. Upon save and close, when I go back in the attribute is stripped out. We need the attribute to remain intact all the way through deployment, or the data table is meaningless in the responsive mobile design.
Example: <tr>
<td data-title="#1 Viewed">most viewed 1</td>
<td> </td>
<td data-title="#1 Post">most popular 1</td>
</tr>
Marketo needs to support HTML5 attributes for responsive tables to work! This is also important for accessibility. Let's make it happen, please!
