使用 JavaScript 和 C++ 显示或隐藏网格线以及行列标题
显示和隐藏网格线
所有Excel工作表默认情况下都有网格线。它们有助于划分单元格,便于将数据输入特定的单元格。网格线使我们能够将工作表视为单元格的集合,其中每个单元格都易于识别。
控制网格线的可见性
Aspose.Cells提供了一个类Workbook,代表一个Microsoft Excel文件。Workbook类包含一个Workbook.worksheets集合,允许开发者访问Excel文件中的每个工作表。工作表由Worksheet类表示。Worksheet类提供了丰富的属性和方法管理工作表。若要控制网格线的显示,请使用Worksheet.isGridlinesVisible()属性。Worksheet.isGridlinesVisible()是一个布尔型属性,只能存储true或false值。
使网格线可见
通过将Worksheet.isGridlinesVisible()属性设置为true,使网格线可见。
隐藏网格线
通过将Worksheet.isGridlinesVisible()属性设置为false,隐藏网格线。
下面给出一个完整示例,展示如何通过打开Excel文件(book1.xls)、隐藏第一个工作表上的网格线,并将修改后的文件另存为output.xls,来使用Worksheet.isGridlinesVisible()属性。

显示和隐藏行列标题
Excel文件中的所有工作表都由排列在行和列中的单元格组成。所有行和列都有用于标识它们和单个单元格的唯一值。例如,行编号为1、2、3、4等,列按字母顺序排列为A、B、C、D等。行和列值显示在标题中。使用Aspose.Cells,开发人员可以控制这些行和列标题的可见性。
控制工作表的可见性
Aspose.Cells提供了一个类Workbook,代表一个Microsoft Excel文件。Workbook类包含一个Workbook.worksheets集合,允许开发者访问Excel文件中的每个工作表。工作表由Worksheet类表示。Worksheet类提供了丰富的属性和方法管理工作表。若要控制行列标题的可见性,请使用Worksheet.isRowColumnHeadersVisible()属性。Worksheet.isRowColumnHeadersVisible()是一个布尔型属性,只能存储true或false值。
使行/列标头可见
通过将Worksheet.isRowColumnHeadersVisible()属性设置为true,使行和列标题可见。
隐藏行/列标头
通过将Worksheet.isRowColumnHeadersVisible()属性设置为false,隐藏行列标题。
下例展示了如何通过打开Excel文件(book1.xls)、隐藏第一个工作表的行列标题,并将修改后的文件另存为output.xls,来使用Worksheet.isRowColumnHeadersVisible()属性。
