You can expose the cell slot in the Table component and use it in App.vue

<!-- Table.vue -->
<template>
  <div class="table">
    <template v-for="(row, rowI) in table.tree" :key="rowI">
      <Row :row="row">
        <template #cell="{ cell }">
          <slot name="cell" :cell="cell"></slot>
        </template>
      </Row>
      <slot name="test" :id="rowI" />
    </template>
  </div>
</template>
