在columns项里增加filters可增加筛选功能，可设置多选或单选，如果有onFilter则客户端进行过滤，如果没有onfilter则会触发table-change事件，自行去服务器端进行过滤

```js
var columns = [{
  title: '姓名ss',
  dataIndex: 'name',
  filters: [{
    text: '姓李的的',
    value: '李',
  }, {
    text: '姓胡的',
    value: '胡',
  }],
  sorter:true,
  width:150,
  onFilter: (names, record) => {
    return names.some(function(name){
      return record.name.indexOf(name) == 0
    })
  }
}, {
  title: '年龄',
  dataIndex: 'age',
  width:250,
  filters: [{
    text: '32',
    value: '32',
  }, {
    text: '42',
    value: '42',
  }]
}, {
  title: '地址',
  dataIndex: 'address',
  filters: [{
    text: '南湖',
    value: '南湖',
  }, {
    text: '西湖',
    value: '西湖',
  }],
  filterMultiple: false,
  width:250,
  onFilter: (value, record) => {
    return record.address.indexOf(value)>=0
  }
},{
    title: '操作',
    key: 'operation'
  }
];
```
