介绍
在本文中，我们将学习如何以编程方式检查Excel工作表的冻结状态。我们可以简单地在MS Excel中查找工作表是否被冻结或拆分。但有没有办法用JavaScript查找是否被冻结或拆分？我们可以用Aspose.Cells for JavaScript通过C++轻松实现。
窗格是否冻结
使用Aspose.Cells for JavaScript通过C++，我们可以检查窗口是否被冻结，以及锁定了多少行和列。
请使用Worksheet.paneState属性来检查窗口窗格的状态，并使用Worksheet.freezedPanes属性获取锁定的行和列。 1.构建工作簿以打开文件。 2.检查工作表是否被冻结。 3. 获取锁定的行和列。
