antd table合并单元格

最近项目中遇到一个问题，antd table的单元格合并问题，并且数据是包含子元素的数据类型。

import React from 'react';
import { Table} from 'antd';
class MyTable extends React.Component {
    renderContent = (value, row, index) => {
        const obj = {
          children: value,
          props: {},
        };
        if (row.isMerge) {
          obj.props.rowSpan = row.rowSpan;
        }
        return obj;
      };
      
      columns = [
        {
          title: '科室',
          dataIndex: 'team',
          render: this.renderContent
        },
        {
          title: '停诊次数',
          dataIndex: 'suspend',
          render: this.renderContent,
        },
        {
          title: '替诊次数',
          dataIndex: 'replace',
          render: this.renderContent,
         
        },
        {
          title: '总计',
          dataIndex: 'count',
          render: this.renderContent,
        },
        {
          title: '联系电话',
          dataIndex: 'phone',
        },
      ];
      
      data = [
