Vue版本：2.6.10
Vuetify版本：1.5
我正在使用Vuetify 1.5.16文档的示例数据：https://v15.vuetifyjs.com/en/components/data-tables
问题在于数组在编辑模式下被编辑（我可以在控制台中看到它），但是它没有显示在vuetify数据表中（除非我改回原先的页面或使用扩展行中的输入字段）。 / p>
该问题可能与axios有某种联系，因为当我只使用常规数据数组时就没有问题。
我正在将Vue.js和Vuetify与Django框架一起使用，但可能对这个问题没有影响。

答案 0 :(得分：0)
beforeCreate()方法是Vue生命周期中的第一个方法。此时，数据没有反应性，因此您在beforeCreate()方法中对数据所做的任何更改都不会反映出来。而是对created()或mounted()方法进行更改。
