防止在使用 JavaScript 通过 C++ 将隐藏工作表内容导出为 HTML 时被导出

您可以将 Excel 工作簿保存为 HTML。但是，如果工作簿包含隐藏的工作表，则 Aspose.Cells 默认情况下会将隐藏的工作表内容导出到 HTML 输出的 (_files) 目录中，该目录包含诸如工作表、图像、tabstrip.htm、stylesheet.css 等文件。有时，以这种方式导出隐藏的工作表内容是不合适的。例如，如果隐藏的工作表包含不应导出到 _files 目录的图像。

Aspose.Cells for JavaScript 通过 C++ 提供了 HtmlSaveOptions.exportHiddenWorksheet 属性。默认情况下，其设置为 true，隐藏的工作表内容会导出为 HTML。如果将其设置为 false，Aspose.Cells 将不会导出隐藏工作表内容。
