  .then(res => res.json())
  .then(data => {
    const columns = [
      {
        field: 'Order ID',
        title: 'Order ID',
        width: 'auto'
      },

        field: 'City',
        title: 'City',
        width: 'auto'
      },
      {
        field: 'Order Date',
        title: 'Order Date',
        width: 'auto'
      },
      {
        field: 'Quantity',
        title: 'Quantity',
        width: 'auto'
      },
      {
        field: 'Sales',
        title: 'Sales',
        width: 'auto'
      },
      {
        field: 'Profit',
        title: 'Profit',
        width: 'auto'
      }
    ];

    const option = {
      records: data,
      columns,
      widthMode: 'standard',
      rightFrozenColCount: 2,
      rowSeriesNumber: {
        title: '序号',
        dragOrder: true,
        width: 'auto',
        headerStyle: {
          color: 'black',
          bgColor: 'pink'
        },
        style: {
          color: 'red'
        }
      }
    };
    tableInstance = new VTable.ListTable(document.getElementById(CONTAINER_ID), option);
    window['tableInstance'] = tableInstance;
  });

执行 window['tableInstance'].rightFrozenColCount = 1; 报错
