    //把索引数组里的值由String转换成Number
    const keys = Object.keys(list)
    const index = [];
    keys.forEach(item=>{
      index.push(Number(item))
    });
    this.handleRowSelectChange(index,list)
  }
  this.setState({ischecked:ischecked})
}
handleRowSelectChange = (selectedRowKeys, selectedRows) => {
