libxl readNum（）在短时间后崩溃
好的。 所以我使用libXLparsing.xlsx文件。 我遇到了一个奇怪的错误，因为当我调用sheet-> readNum（row，col）函数时，它完成了它的工作，但是只有45-47次。 我检查了很多文件。 检查了.xls和.xlsx。 完成多个debugging会话。 在〜45 readNums（）之后，readNum（）函数返回0，而不是站在这里的实数。 好的，这里是我的代码：（不要看couts，为我公司的人力资源服务）

这不是一个崩溃。
libxl的官方网页说：
它会在每个电子表格的第一行写一个横幅，它将只能读取100个单元格（第一行不可用）。 购买许可证密钥以删除横幅和读取限制
