I have an issue where Thunderbird is not clearing the inner tables based on the parent width.
The top image shows how it should look and the bottom shows how it looks in Thunderbird.
<table cellpadding="0" cellspacing="0" border="0">
<tr>
<td valign="top">
<table cellpadding="0" cellspacing="0" border="0" align="center" style="max-width: 600px; width: 100%; table-layout: fixed; background: red;">
<tr>
<td valign="top">
<table cellpadding="0" cellspacing="0" border="0" align="left" style="width: 100px; table-layout: fixed; background: blue;">
<tr>
<td>test</td>
</tr>
</table>
<table cellpadding="0" cellspacing="0" border="0" align="left" style="width: 100px; table-layout: fixed; background: blue;">
<tr>
<td>test</td>
</tr>
</table>
<table cellpadding="0" cellspacing="0" border="0" align="left" style="width: 100px; table-layout: fixed; background: blue;">
<tr>
<td>test</td>

If I change the inner tables to a really long paragraph then the text wraps as expected. I need to tables to simple float next to each other so that it works in Outlooks or phones that dont support media queries.
This live example shows it working correctly in Firefox: http://codepen.io/anon/pen/ioBdw
