title: Python 3: pretty_html_table returning HTML text rather than table
body: <p>I'm writing a script to email a pandas dataframe as a table to several people. I have my dataframe <code>frame</code>:</p>
  <pre><code>     SITE  ...   VISITS
  438     1  ...      104
  439     2  ...      104
  440     3  ...      104
  504     4  ...      215
  </code></pre>
  <p>I'm trying to create a pretty_html_table that I can email using:</p>
  <pre><code>from pretty_html_table import build_table
  
  html_table = build_table(frame, 'blue_light')
  </code></pre>
  <p>However, instead of emailing a table, the script emails a bunch of html text!</p>
  <pre><code>&lt;p&gt;&lt;table border=&quot;0&quot; class=&quot;dataframe&quot;&gt;
    &lt;thead&gt;
      &lt;tr style=&quot;text-align: right;&quot;&gt;
        &lt;th style = &quot;background-color: #FFFFFF;font-family: Century Gothic;font-size: medium;color: #305496;text-align: left;border-bottom: 2px solid #305496;padding: 0px 20px 0px 0px&quot;&gt;SITE&lt;/th&gt;
  etcetera, etcetera ...     
  </code></pre>
  <p>I'm trying to append this table to an email like so:</p>
  <pre><code>import win32com.client as win32
  
  def report_email(email):        
      html_table = build_table(frame, 'blue_light')
      
      outlook = win32.Dispatch('outlook.application')
      mail = outlook.CreateItem(0)
      mail.To = email
      mail.Subject = 'Table below'
      mail.Body  = &quot;Hi, here is a table&quot; + html_table
      
      return mail.Send()
  </code></pre>
  <p>Thanks so much for all you help!</p>
