title: How to use both v-slot:item and v-slot:item.<name> in Vuetify data table?
body: <p>I've got a fairly customized Vuetify data table that I'm using, in that I've overwritten several columns with custom variations:</p>
  
  <pre><code>&lt;v-data-table
      :headers="headers"
      :items="category.items"
      hide-default-footer
      show-select
      single-select
      sort-by="position"
      sort-desc&gt;
      &lt;template v-slot:item.data-table-select="{ item }"&gt;
          &lt;v-icon
              class="handle grab"&gt;
              mdi-drag-vertical
          &lt;/v-icon&gt;
      &lt;/template&gt;
  
      &lt;!-- Type Edit In Place --&gt;
      &lt;template v-slot:item.generic_type="{ item }"&gt;
          &lt;span
              v-if="editableItem !== `type${item.id}Ref`"
              @click="setEditing(`type${item.id}Ref`);"&gt;
              {{ item.generic_type }}
          &lt;/span&gt;
          &lt;v-text-field
              v-else
              :ref="`type${item.id}Ref`"
              :value="item.generic_type"
              color="primary"
              dense
              hide-details
              type="text"
              outlined
              @blur="updateItem($event.target.value, item, 'generic_type')"
              @change="updateItem($event, item, 'generic_type')" /&gt;
      &lt;/template&gt;
  
      // Several others similar to the input above //
  
  &lt;/v-data-table&gt;
  </code></pre>
  
  <p>Now though I'm trying to implement SortableJS, and am needing to be able to add a custom data attribute to each row of the data table so that I can reference it later in my Sortable functions. </p>
  
  <p>According to the <a href="https://vuetifyjs.com/en/components/data-tables#slots" rel="noreferrer">Vuetify docs</a>, <code>Some slots will override each other such as: body &gt; item &gt; item.&lt;name&gt; and header/header.&lt;name&gt;.</code></p>
  
  <p>How do I go about writing a custom table row so that I can attach custom data attributes, as well as keeping the existing table columns that I've custom written?</p>
