title: Pandas to_html float_format
body: <p>I've the following dataframe:</p>
  
  <pre><code>CLIENT | AMOUNT
  N130   | 1000.50
  </code></pre>
  
  <p>And want to insert it into an email.</p>
  
  <pre><code>var = df.to_html(header=True, index=False, na_rep="", float_format="{:,}".format)
  </code></pre>
  
  <p>The problem is that the amount has the format 1,000.50 and what I pretend is the exact opposite 1.000,50.</p>
  
  <p>I've also tried to format the column AMOUNT using .apply but with no success. Can someone help me with this problem. Thanks in advance.</p>
