Ag grid groupSuppressAutoColumn不使用动态columnDef-ag栅格角度

我正在尝试使用“agGroupCellRenderer”创建自定义行分组。但使用“行组”面板拖动功能创建新行组后，栅格数据将消失

我正在尝试更新columnDef

columnRowGroupChanged(event) {

this.columnDefs = [
  {
    headerName: 'Country',
    minWidth: 200,
    showRowGroup: 'country',
    cellRenderer: 'agGroupCellRenderer',
  },
  {
    headerName: 'Year',
    minWidth: 200,
    showRowGroup: 'year',
    cellRenderer: 'agGroupCellRenderer',
  },
  {
    headerName: 'athlete',
    minWidth: 200,
    showRowGroup: 'athlete',
    cellRenderer: 'agGroupCellRenderer',
  },
  {
    field: 'country',
    rowGroup: true,
    hide: true,
  },
  {
    field: 'year',
    rowGroup: true,
    hide: true,
  },
  {
    field: 'athlete',
    rowGroup: true,
    hide: true,
  },
  { field: 'gold' },
  { field: 'silver' },
  { field: 'bronze' },
];

}
