如何在element-ui中手动调用filterHandler？

Question

加载页面时，我需要默认检查某些过滤条件。我已经通过this。$ refs.tableRC.columns [0] .filteredValue = this.filteredBranch设置了默认值，但是我不知道如何手动调用filterHandler（）来过滤表数据？

<el-table ref="tableRC" :data="datalist" @filter-change="tableFilter">
  <el-table-column label="Branch" :filters="branches" :column-key="'branch'" :filter-method="filterHandler">

......

tableFilter(filters) {
  this.filteredBranch = filters.branch
},
filterHandler(value, row, column) {
  return row.branch === value
},
getReqList() {
  ....
  this.$refs.tableRC.columns[0].filteredValue = this.filteredBranch
  ....
}

最后，我找到了解决方法

    if (Object.prototype.toString.call(this.filteredBranch) === '[object Array]') {
      this.$refs.tableRC.columns[x].filteredValue = this.filteredBranch
      this.$refs.tableRC.store.states.columns.forEach(column=> {           
        if (column.filteredValue && column.filteredValue.length) {
          this.$refs.tableRC.store.commit('filterChange', {
            column,
            values: column.filteredValue,
            silent: true
          })
        }
      })
    }
