el-table的上下筛选功能

el-table的sort-change事件可以监听到筛选的事件； 

会返回prop属性和order排序的顺序；

html：

<el-table :data="tableData" border style="width: 100%" :cell-style="{ textAlign: 'center' }"header-cell-class-name="table-th" row-key="id" @sort-change="sortChange"><el-table-column prop="look_number" label="浏览次数" sortable="custom" /><el-table-column prop="number" label="点赞人数" sortable="custom" />
</el-table>

js：

/** * 排序改变
*/
sortChange(e) {let params = {};if (e.prop == "look_number" && e.order && e.order == "ascending") {params.look_number = 1;} else if (e.prop == "look_number" && e.order && e.order == "descending") {params.look_number = 2;} else if (e.prop == "number" && e.order && e.order == "ascending") {params.number = 1;} else if (e.prop == "number" && e.order && e.order == "descending") {params.number = 2;}
}
