title: Table does not show row and column borders in email sent using PHP mail
body: <p>I am using PHP to send mail of a webpage content. I have a table in the page.
  My table does not show row and column borders in email sent using PHP mail.
  It does not read the CSS in email. 
  This is my code:</p>
  
  <pre><code>&lt;div id="table_email" style="width:800px;margin-left:50px; text-align: left;"&gt;
      &lt;table class="table1"&gt;
          &lt;tr&gt;
              &lt;th&gt;Description&lt;/th&gt;
              &lt;th colspan="2"&gt;Amount&lt;/th&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;(A)Package Cost&lt;/td&gt;
              &lt;td&gt;';$formatedMessag .= $inv[0].'&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;(B) Insurance &lt;/td&gt;
              &lt;td&gt;';$formatedMessag .= $inv[1].'&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;(C)Flight / Train&lt;/td&gt;
              &lt;td&gt;';$formatedMessag .= $inv[2].'&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;Add : &amp;emsp;Service Tax 3% on Rs.(a+b)&lt;/td&gt;
              &lt;td&gt;';$formatedMessag .=$inv[5].'&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;Add : &amp;emsp;Educational Cess 2% On 3% &lt;/td&gt;
              &lt;td&gt;';$formatedMessag .= $inv[6].'&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr&gt;
              &lt;td&gt;Add : &amp;emsp;Secondary&amp; Higher Education Cess 1% on 3% &lt;/td&gt;
              &lt;td&gt;';$formatedMessag .= $inv[7].'&lt;/td&gt;
          &lt;/tr&gt;
          &lt;tr style=" font-weight: bold;font-size: 12px;background-color:seashell;"&gt;
              &lt;td&gt;Total Payable Amount&lt;/td&gt;
              &lt;td&gt;';$formatedMessag .='INR ' . $inv[9].'&lt;/td&gt;
          &lt;/tr&gt;
          ';$formatedMessag .='
      &lt;/table&gt;
  &lt;/div&gt;
