{% regroup column_list_bottom_left by 국내해외 as data0 %}
    {% for eachDom in data0 %}
        {% regroup eachDom.list by 본부 as data1 %}
            {% for eachBonbu in data1 %}
                {% regroup eachBonbu.list by 현장 as data2 %}
                    {% for eachSite in data2 %}
                        <!-- 각 줄별로-->
                        {% for rowData in eachSite.list %}

                                    {% if forloop.parentloop.first %}
                                        {% if forloop.parentloop.parentloop.first %}
                                            <td class="data" rowspan="{{eachDom.list|length}}"><div class="align-center ellipsis" style="width:100px;">{{eachDom.grouper}}</div></td>
