element-UI + vue table remote sorting&& manual intervention sorting

Table remote sorting:

The attribute to be sorted is added: sortable='custom'

table added: @sort-change='sortChange'

Page bug:

  el-table(
    :data='dataList'
    border
    @sort-change='sortChange'
  )
    el-table-column(prop='ruleId' label='配置编号' align='center' sortable='custom' width='120')
    ...
    el-table-column(prop='lastUpdateTime' label='最后修改时间' align='center' width='140' sortable='custom')

js：

    // 监听表头点击获取排序参数
    sortChange(column) {
      const { order = '', prop = '' } = column;
      this.loadData(order, prop);
    },

Agree with the backend to request data function interface to add parameters:

    loadData(order = 'descending', prop = 'lastUpdateTime') { // 加载数据
      const params = {
        ...
        'orderBy.property': prop, 
        'orderBy.direction': order === 'ascending' ? 'asc' : 'desc',
      };
      ...
    },

When there are two props to be sorted in the table header, specify the default sorting method:

Add attribute to html:: default-sort='defaultSort'

  el-table(
    :data='dataList'
    border
    @sort-change='sortChange'
    :default-sort='defaultSort'
  )

js：

defaultSort: {
    prop: 'lastUpdateTime',
    order: 'descending',
},

When clicking another prop to sort and then click the query button, how can I manually intervene to change the selected state of the sort to the default sorted prop:

table setting ref:

  el-table(
    :data='dataList'
    border
    @sort-change='sortChange'
    :default-sort='defaultSort'
    ref="table"
  )

js：

search() { // 搜索数据
 this.loadData();
 this.$refs.table.sort('lastUpdateTime', 'descending'); // 手动修改table排序按钮选中状态
},
