我需要加载远程表时的勇气

问题是什么.. ???

感谢。

当您使用“此操作”注释查找行计数时，行计数尚不可用，因为尚未发出从服务器检索行计数的网络操作。

您可能希望监听模型的dataChanged事件，该事件在加载行计数或模型数据更改时触发，例如：

TableRegiones.getTableModel().addListener(
  'dataChanged',
  function ()
  {
    console.log(
      "dataChanged: RTRegionesModel.getRowCount(): %s",
      RTRegionesModel.getRowCount());
  },
  RTRegionesModel);
