title: How do I display currency in a Flask Table generated table column?
body: <p>flask-table does have several specific column types. For example date: DateCol. But there is no column type for currency. So for now data is displayed using the standard Col type. Now you just get a Decimal. It works but I'd would prefer a currency format.</p>
  
  <p>Table.py</p>
  
  <pre><code># import things
  from flask_table import Table, Col, DateCol
  
  # Declare my table
  class MyTable(Table):
      classes = ['table', 'table-hover']
      id = Col('id')
      amount = Col('amount')
      date = DateCol('date')
  </code></pre>
  
  <p>template.html</p>
  
  <pre><code>&lt;div&gt;{{ amounts_table }}&lt;/div&gt;
  </code></pre>
  
  <p>routes.py</p>
  
  <pre><code>@route('/my_table')
  def my_table():
      table_content = Amounts.query.all()
      amounts_table = AmountsTable(table_content)
      return render_template('template.html', amounts_table=amounts_table)
  </code></pre>
  
  <p>result:</p>
  
  <pre><code>id     amount       date
  1      1,523.78     30-03-2019
  </code></pre>
  
  <p>what I would like to accomplish:</p>
  
  <pre><code>id     amount       date
  1      € 1.523,78   30-03-2019
  </code></pre>
