Email signature not showing up properly in email

Question

I have created an html signature and it looks good on desktop but on mobile the last image is breaking into a new line when it should be directly next to the social media icons. Is there something I can include in the code to make the table row not break into a new line?

Here is the code:

<style>
    table {border-spacing: 0; width:500px; display:block; line-height:0; }
  #container{width:500px; height:167px}
  </style>


<div id="container">
  <table width="500" cellpadding="0" cellspacing="0">
    <tr>
      <td width="100%" bgcolor="#000"><img src="https://dl.dropboxusercontent.com/u/2693031/1.gif" width="500" height="76" style="display:block" alt="Cynthia Larenas Freelance Designer &amp; video artist"/></td>
    </tr>
    <tr>
      <td width="100%" bgcolor="#000"><a href="http://www.cynthialarenas.com" target="_blank"><img src="https://dl.dropboxusercontent.com/u/2693031/2.gif" width="500" height="26" style="display:block"   alt="www.cynthialarenas.com"/></a></td>
    </tr>
    <tr>
      <td width="100%" bgcolor="#000">
        <a href="http://www.twitter.com/cynthialarenas" target="_blank"><img src="https://dl.dropboxusercontent.com/u/2693031/3.gif" width="57" height="68" style="display:inline" alt="Twitter"/></a>

    </tr>
  </table>
