title: antd: error TS2339: Property 'centered' does not exist on type
body: <pre><code>&lt;Modal visible={this.state.showModel} title="添加代金券"
                        centered
                        okText="保存" cancelText="取消"
                        onOk={() =&gt; this.okBtnClick}
                        onCancel={() =&gt; this.cancelClick}
  &gt;
  </code></pre>
  
  <p>I use ANTD's modal to make it vertically centered, but I was wrongly told that centered does not exist and attribute 1.</p>
