业务场景:表格有”发布时间“一列,发布时间可以点击上下箭头排序(和后台交互排序所有数据,非当前表格里的几条)。
html:
<el-table :data="tableData" style="width: 100%" @sort-change="sortChange">
<!-- sortable="custom"很重要 -->
<el-table-column prop="publishTime" sortable="custom" label="发布时间" > </el-table-column>
</el-table>
js:
sortChange(column) {
//打印可以分别得到上下箭头的数据
console.log(column);
if (column.order == "ascending") {
this.orderBy = "+";//根据自己的业务需求来
} else if (column.order == "descending") {
this.orderBy = "-";
} else {
this.orderBy = "";
}
//有多列排序时会用到
// if (column.prop == "publishTime") {
// this.key = "publish_time ";
// } else if (column.prop == "updateTime") {
// this.key = "update_time";
// } else {
// this.key = "";
// }
this.currentPage = 1;
this.searchData();//查询列表方法
},
