Looker Table Calculation to get rendered value of a column

[CodeVision79]

Hello Team,
I'm seeking guidance on a specific aspect of LookML related to a measure I'm working on. My goal is to get the rendered value in table calculation i.e., HTML properties in the following example.

When attempting to retrieve the entire text, including the HTML formatting, I'm only able to access the numeric value derived from the SQL portion of the measure. Is there a method within the table calculation to obtain the entire text (rendered value), encompassing the HTML formatting, rather than solely the SQL-derived DAU? Your insights and suggestions on this matter would be greatly appreciated.
Thank you,

Example Measure:

  measure: dau {
    type: sum
    sql: ${TABLE}."DAU";;
    html: {{ rendered_value }} {% if flag_description._value != null and flag_description._value != "" %}
          
          Event Flags:
          
          =======================
           
          {% assign flag_descriptions = flag_description._value | split: ';' %}
          {% for description in flag_descriptions %}
            {{ description }} <br/>
          {% endfor %}
        {% endif %} ;;
  }

accessing the field from table calculation like following does not give html rendered part:
