React antd Descriptions span属性无效问题

label=“Status” span={3}，但是span为3无效

<Descriptions title="User Info" layout="vertical" bordered>
    <Descriptions.Item label="Product">Cloud Database</Descriptions.Item>
    <Descriptions.Item label="Billing Mode">Prepaid</Descriptions.Item>
    <Descriptions.Item label="Automatic Renewal">YES</Descriptions.Item>
    <Descriptions.Item label="Order time">2018-04-24 18:00:00</Descriptions.Item>
    <Descriptions.Item label="Usage Time">
      2019-04-24 18:00:00
    </Descriptions.Item>
    <Descriptions.Item label="Status" span={3}>
      <Badge status="processing" text="Running" />
    </Descriptions.Item>
    <Descriptions.Item label="Negotiated Amount">$80.00</Descriptions.Item>
    <Descriptions.Item label="Discount">$20.00</Descriptions.Item>
    <Descriptions.Item label="Official Receipts">$60.00</Descriptions.Item>
    <Descriptions.Item label="Config Info">
      Data disk type: MongoDB
      <br />
      Database version: 3.4
      <br />
      Package: dds.mongo.mid
      <br />
      Storage space: 10 GB
      <br />
      Replication factor: 3
      <br />
      Region: East China 1<br />
    </Descriptions.Item>
  </Descriptions>

原因：span={3} 这项，前面的span的总和需要是column的倍数，在上个例子中，
label="Status"前面的span总和为5，所以无效

解决方法：我是在动态值渲染中出现的这个问题
在label="Status"前面加一个

<Descriptions.Item span={column} />

其中column为Descriptions中column的值
