How to build an HTML table using a for loop in Flask?

{% for sketch in testing_sketches %}

    {% for i in range(split_reconstructions[loop.index0] | count) %}
    
    {% endfor %}
  
      {% for addr in split_reconstructions[loop.index0] %}
      
      {% endfor %}
    

  

    
Image
Reconstruction-{{i+1}}
  
    

      
{{ sketch }}
{{ addr }}
  

{% endfor %}
