如果DataGridView绑定到数据源，那么我认为你不能这样做。 使用未绑定的数据，您可以插入空行，但是对于绑定数据，您将需要空记录，这可能会使底层数据源变得混乱（如果
甚至允许，例如，您不能在其中包含任何必填字段绑定数据源）

If the DataGridView is bound to a data source then I don't think you'll be able to do this.  With unbound data you could insert empty rows, but with bound data you would need empty records and that could make a mess of the underlying data source (if it was even allowed e.g. you couldn't have any required fields in the bound data source)
