HTML CSS How to stop a table cell from expanding

It appears that your HTML syntax is incorrect for the table cell. Before you try the other idea below, confirm if this works or not... You can also try adding this to your table itself: table-layout:fixed.. .

<td style="overflow: hidden; width: 280px; text-align: left; valign: top; whitespace: nowrap;">
   [content]
</td>

New HTML

<td>
   <div class="MyClass"">
       [content]
   </div>
</td>

CSS Class:

.MyClass{
   height: 280px; 
   width: 456px; 
   overflow: hidden;
   white-space: nowrap;
}

To post Chris Dutrow's comment here as answer:

style="table-layout:fixed;" 

in the style of the table itself is what worked for me. Thanks Chris!

Full example:

<table width="55" height="55" border="0" cellspacing="0" cellpadding="0" style="border-radius:50%; border:0px solid #000000;table-layout:fixed" align="center" bgcolor="#152b47">
  <tbody>
    <td style="color:#ffffff;font-family:TW-Averta-Regular,Averta,Helvetica,Arial;font-size:11px;overflow:hidden;width:55px;text-align:center;valign:top;whitespace:nowrap;">

     Your table content here

    </td>
  </tbody>
</table>

<table border="1" width="183" style='table-layout:fixed'>
  <col width="67">
  <col width="75">
  <col width="41">
  <tr>
    <td>First Column</td>
    <td>Second Column</td>
    <td>Third Column</td>
  </tr>
  <tr>
    <td>Row 1</td>
    <td>Text</td>
    <td align="right">1</td>
  </tr>
  <tr>
    <td>Row 2</td>
    <td>Abcdefg</td>
    <td align="right">123</td>
  </tr>
  <tr>
    <td>Row 3</td>
    <td>Abcdefghijklmnop</td>
    <td align="right">123456</td>
  </tr>
</table>

I know it's old school, but give that a try, it works.

may also want to add this:

<style>
  td {overflow:hidden;}
</style>

Of course, you'd put this in a separate linked stylesheet, and not inline... wouldn't you ;)
