Thanks… Work fine after create a computed propìerty for columns

columnsI18n () {
      let columns = [
        {
          name: 'domain',
          required: true,
          label: this.$t('domains.label'),
          align: 'left',
          field: row => row.domain,
          format: val => `${val}`,
          sortable: true
        },
        {
          name: 'active',
          align: 'center',
          label: this.$t('domains.active'),
          field: row => row.active,
          format: val => String(!!val),
          sortable: true
        },
        {
          name: 'show',
          align: 'center',
          sortable: false
        },
        {
          name: 'edit',
          align: 'center',
          sortable: false
        },
        {
          name: 'archive',
          align: 'center',
          sortable: false
        },
        {
          name: 'delete',
          align: 'center',
          sortable: false
        }
      ]
      return columns
    }
