Ant design table row merge based on data instead of index value

问题

 {
    title: 'Home phone',
    colSpan: 2,
    dataIndex: 'tel',
    render: (value, row, index) => {
      const obj = {
        children: value,
        props: {},
      };
      if (index === 2) {
        obj.props.rowSpan = 2;
      }
      // These two are merged into above cell
      if (index === 3) {
        obj.props.rowSpan = 0;
      }
      if (index === 4) {
        obj.props.colSpan = 0;
      }
      return obj;
    },
  },

In dis example based on index value rowsspan size is decided, can we do that based on previous column data (if there are two John Brown's then row span should be 2)?. So basically we need to decide row span size by sorting rows and comparing row value.
