如何在 Vuetify 中使用 v-slot 在动态列之间迭代
How can I iterate between dynamic columns with v-slot in Vuetify
我在 data-table 中有动态变化的列。例如 col1、col2、col3 值列。我怎样才能动态地制作 <template v-slot:item.col1="item"> and <template v-slot:item.col2="item">....
您可以在 table 中添加多个模板。因此,您可以为 table.
中的每个列定义一个
这是 vuetify 中沙漠示例的工作示例 API。
