What you'll want to do is use a Media Query to check whether the screen size is less than a certain size to display responsive layouts. e.g:
#media only screen and (max-width: 500px;) {
//Responsive CSS styling
}
Using this you can center those tables as you would with a normal webpage. e.g:
#media only screen and (max-width: 500px;) {
td[class="responsive-align"] {
margin: 0 auto !important;
float: none !important;
align: center !important; //If this line centers your text, remove it.
}
}
Email clients are very pedantic, and take a long time to understand what you can do with each one, and what their limits are.
From my experience with responsive designs and Outlook especially you need to lay out your tables like this for them to drop down effectively:
<table align="left">
<tr>
<td>
</td>
</tr>
</table>
<table align="right">
<tr>
<td>
</td>
</tr>
</table>
With Outlook, it's best to make sure you have 5px or larger in between the two tables so that it can add it's own spacing in (That you can't do anything about). So, for a table of 600px width, you'd have each of your tables with a width of 295px for a good enough amount of spacing.
Hope this helps :)
