How to make Vuetify HTML table fully bordered?

I have a Vue app consuming a Vuetify table that doesn’t support bordered tables ( yet, see https://github.com/vuetifyjs/vuetify/issues/16336 ). That’s why I tried my own CSS to add the missing borders.

Given the following sample ( Reproduction link )

<template>
  <v-app>
    <v-main>
      <v-table>
        <thead>
          <tr>
            <th>Col 1</th>
            <th>Col 2</th>
          </tr>
        </thead>
        <tbody>
          <tr v-for="(row, rowIndex) in tableMatrix" :key="rowIndex">
            <template v-for="(cell, columnIndex) in row" :key="columnIndex">
              <td v-if="cell.isCoveredByPreviousCell" class="d-none" />
              <td v-else :rowspan="cell.rowspan">
                <template v-if="cell.content">
                  {{ cell.content }}
                </template>
              </td>
            </template>
          </tr>
        </tbody>
      </v-table>
    </v-main>
  </v-app>
</template>

<script setup lang="ts">
import { ref, Ref } from 'vue';

interface Cell { isCoveredByPreviousCell: boolean; rowspan: number; content?: string; }

type TableMatrix = Cell[][];

const childCell: Cell = { isCoveredByPreviousCell: false, rowspan: 1, content: "cell with rowspan 1" };

const tableMatrix: Ref<TableMatrix> = ref([
  [{ isCoveredByPreviousCell: false, rowspan: 2, content: "cell with rowspan 2" },{ ...childCell }],
  [{ isCoveredByPreviousCell: true, rowspan: 1, content: "covered by parent" },{ ...childCell }],
  [{ ...childCell },{ ...childCell }],
  [{ ...childCell }, { isCoveredByPreviousCell: false, rowspan: 2, content: "cell with rowspan 2" }],
  [{ ...childCell }, { isCoveredByPreviousCell: true, rowspan: 1, content: "covered by parent" }],
  [{ isCoveredByPreviousCell: false, rowspan: 2, content: "cell with rowspan 2" },{ ...childCell }],
  [{ isCoveredByPreviousCell: true, rowspan: 1, content: "covered by parent" },{ ...childCell }],
])
</script>

<style>
table { border: 1px solid #e6e6e6; }
  
table th { border-top: 1px solid #e6e6e6; }

table th + th { border-left: 1px solid #e6e6e6; }

table td + td { border-left: 1px solid #e6e6e6; }
</style>

You can see that the last cell has a thicker border if it has a rowspan greater than 1

enter image description here

Does someone know which CSS "rule" is missing to fix the table border for this case?

    Uses the slot=item, then apply the styles depending on scoped-slot.

    Below is one example:

    Show code snippet

    Uses the slot=item.name.

    new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data () {
    return {
      headers: [
        {

    Simply add the border-collapse: collapse; property to the table.

    table {
  border-collapse: collapse;
}

    The border-collapse property sets whether table borders should
    collapse into a single border or be separated as in standard HTML.
