NPOI / POI Excel Lib ISheet.ShiftRows 索引超出范围异常
NPOI / POI Excel Lib ISheet.ShiftRows Index Out of Range Exception
我在 NPOI 中使用 .ShiftRows 将新行插入到 Excel 文件中。但是，当我尝试向下移动行以插入新行时，我在某些文件上得到了 System.ArgumentOutOfRangeException。这些只是我正在填充的来自不同公司的通用文件，因此它们可能不是 "clean" 即底部的空白行等。我希望它仍然是 运行 不管怎样因为 NPOI 知道最后一行在哪里。
在这种情况下，我将第 16 行向下移动到第 458 行并得到了超出范围的异常。

有没有人运行以前用 NPOI 或 POI 解决过这个问题？
使用 NPOI v2.2.1.
编辑：我将同一个文件保存为 .xls（以前为 .xlsx），但没有出现问题。可能仅与 XSSFWorkbook 的 .ShiftRows 有关...将继续让您发布。
此问题已在 NPOI V2.3.0.
中修复
