Django. How to display in admin panel?

Question

Django

In the Django admin there is a certain display of objects (in two columns): Value1 Value group1 Value2 Value group1 Value3
Value group2 Value4
Value group3 Value5
Value group3 ... I want to convert it to: Value group1 -Value1 -Value2 Value group2 -Value3 Value group3 -Value4 -Value5 In the database, the "values" field has a foreignkey for "value group" To do this, I decided to override admin change_list_result.html in which I wanted to display the table in the desired form.
The following code in change_list_result.html is now responsible for displaying objects in the admin panel:

{% for result in results %}
{% if result.form.non_field_errors %}
    <tr><td colspan="{{ result|length }}">{{ result.form.non_field_errors }}</td></tr>
{% endif %}

<tr class="{% cycle 'row1' 'row2' %}">{% for item in result %}{{ item }}{% endfor %}</tr>
{% endfor %}

How to be further? Or what other ways to solve the problem?
