请问antdesignvue表格的某列数据如何以降序的形式呈现（后端并无排序）
如图，想要实现在“新增”那一列数据中的数据按降序排列，并不想应用sorter方法，因为这个还需要交互调整，希望默认就是以降序的形式展现，请赐教
用sorter会使表格样式不统一，希望渲染时就呈现降序的数据，请指教，万分感激。

回答：
可以在设置数组之前,对数组进行排序
this.dangerousPlace = temp.sort((a, b) => b.today.confirm - a.today.confirm)以上是 请问antdesignvue表格的某列数据如何以降序的形式呈现（后端并无排序） 的全部内容， 来源链接： utcz.com/p/935991.html
