antd vue 分页异步的数据总total总是拿不到数据请问怎么处理

Question

可能接口是异步的，数据没过来分页就加载了，请问遇到过的朋友怎么出处理呢

    
        
<a-table :data-source="dataList" bordered :pagination="pagination" size="middle">      

                    
data() {
  return {
    pagination: {
      defaultPageSize: 5,
      showQuickJumper: true,
      showTotal: total => `共 ${total} 条数据`,
      showSizeChanger: true,
      pageSizeOptions: ['5', '10', '20', '50'],
      onShowSizeChange: (current, pageSize) => this.onSizeChange(current, pageSize),
      onChange: (current, pageSize) => this.changePage(current, pageSize),
      total: 0
    },
    dataList: []
  }
},
methods: {
   fetchList() {
    getUserList({ ...this.page, ...params }).then(res => {
      const { status, data } = res
      console.log(res)
      if (status === '1' && data) {
        this.dataList = data.content
        this.total = data.total //这里赋值总条数，总是拿不到
      }
    })
  }
}
