用JavaScript通过C++指定共享公式的最大行数

可能的使用场景
默认共享公式的最大行数是 64。可以设置任何数字，例如1000。不同的行数会影响共享公式的性能。因此，Aspose.Cells 提供了 WorkbookSettings.maxRowsOfSharedFormula 属性，可以用来指定共享公式的最大行数。如果总行数超过设置的数值，共享公式将被拆分成多个共享公式，如下图所示。
指定共享公式的最大行数
以下示例代码演示了 WorkbookSettings.maxRowsOfSharedFormula 属性的使用。它将共享公式的最大行数设置为 5，并在单元格 D1 中添加了 100 行的共享公式，保存为 输出Excel文件。 若解压输出Excel文件内容并检查 sheet1.xml，你会看到共享公式每5行分割一次，如上述截图所示。
