注意:expandIcon="expandIcon"， 其中expandIcon需要在methods中定义

 expandIcon(props) {
      if (props.expanded) {
        return (
          <a-icon
            title="点击关闭详细"
            type="minus"
            onClick={(e) => {
              props.onExpand(props.record, e);
            }}
          />
        );
      } else {
        return (
          <a-icon
            title="点击查看详细"
            type="plus"
            onClick={(e) => {
              props.onExpand(props.record, e);
            }}
          />
        );
      }
    },
