element ui table 增加筛选的方法示例

<el-table-column v-for="item in tableHead" :key="item.id" :prop="item.id" :label="item.label" :filters="item.filter" :filter-method="item.filter && filterHandler">

this.tableHead = [
   {id: '1', label: xxx},
   {id: '2', label: xxx, filter: []},
   {id: '3', label: xxx, filter: []},
   {id: '4', label: xxx},
   {id: '5', label: xxx},
   {id: '6', label: xxx, filter: []}
  ]

:filters="[{ text: '家', value: '家' }, { text: '公司', value: '公司' }]"

let filterList = this.tableHead.filter(i => i.id === '1')[0].filter

this.tableData.forEach((item) => {
   filterList.push({
   text: item.xxx, value: item.yyy
  })
 })

uniqArrObject (arr) {
  let result = {}
  let finalResult = []
  for (let i = 0; i < arr.length; i++) {
   result[arr[i].text] = arr[i]
  }
  for (let key in result) {
   finalResult.push(result[key])
  }
  return finalResult
 },

filterList = this.uniqArrObject(filterList)

filterHandler (value, row, column) {
  const property = column['property']
  return row[property] === value || row[property].value === value
},
