Java 您可以使用查看您在行中的位置，而不是通过cellNumber++

自己进行计数。这是由Microsoft设计的Excel文件格式，Excel稀疏地存储单元格，即仅存储已定义的单元格，而不是现有单元格之间的空单元格

因此，没有计划在ApachePOI中改变这一点。您的代码需要对此进行调整，Row.getCell（）将为此类单元格返回null。迭代器不会返回这些空单元格

迭代时，您可以使用查看行中的位置，而不是通过

cellNumber++

@AxelRichter进行自己的计数。此时，我没有阅读任何内容。这是中行中所有单元格的屏幕iterator@AxelRichter添加一个代码。@AxelRichter这是一个问题，是否可以以某种方式更正此问题，是否有任何选项可以解释为什么无法从中获取这些单元格Excel@AxelRichter在这一点上，我没有读任何东西。这是中行中所有单元格的屏幕iterator@AxelRichter添加一个代码。@AxelRichter这是一个问题，这个问题是否可以以某种方式更正，是否有任何选项可以解释为什么无法从Excel中获取这些单元格这实际上是一个很好的答案。我花了几个小时来解决隐藏电池的问题，我们不应该把它算是最好的答案。这实际上是一个非常好的答案。我花了几个小时来解决隐藏电池的问题，我们不应该认为这是最好的答案。
