Add button action in q-table

[eloy.silva]

Hello everyone
I need to add an action button to my table, but it doesn’t show in the final result

<q-table
        dense
        :data="AppGroupUserList"
        :columns="columns"
        row-key="USR_ERP_ID"
        separator="horizontal"
         :visible-columns="visibleColumns"
      >
        <template v-slot:top-right>
          <q-btn color="primary" icon-right="delete_forever" no-caps />
        </template>
        <template v-slot:body-cell-action="props">
          <q-td :props="props">
            <q-btn
              color="negative"
              icon-right="delete"
              no-caps
              flat
              dense
              @click="deleteval(data.indexOf(props.row))"
            />
          </q-td>
        </template>
      </q-table>

I answer myself
add in columns:

{ name: 'action', label: 'Action', field: 'action' }
