Register $t globally

Please register $t globally per default. Now we need each time:

import Vue from 'vue'
const $t = Vue.t
// before we can use:
var title = $t("header.title")

Did you try add return keyword in factory function?

default() {
  return this.$t('close');
},

I am not sure if this is helpful, but I use something like this successfully:

export default {
  data: function () {
    return {
      // just some example of an array with translated labels
      pricesHeader: this.$i18n.t('prices.header'),
      fields: [
        { key: 'label', label: this.$i18n.t('prices.label') },
        { key: 'service', label: this.$i18n.t('prices.info') },
        { key: 'tokens', label: this.$i18n.t('prices.tokens') }
      ]
    }
  }
}
