隐藏和显示行和列

有时，隐藏工作表中的某些行或列并稍后显示它们是有意义的。 Microsoft Excel 提供此功能，Aspose.Cells 也提供此功能。

控制行和列的可见性

Aspose.Cells提供了一个类，工作簿，代表一个 Microsoft Excel 文件。这工作簿类包含一个工作表集合允许开发人员访问 Excel 文件中的每个工作表。工作表由工作表班级。这工作表类提供了Cells代表工作表中所有单元格的集合。这Cellscollection 提供了多种方法来管理工作表中的行或列。下面讨论其中的一些。

隐藏行和列

开发人员可以通过调用隐藏行和隐藏列的方法Cells分别收藏。这两种方法都将行和列索引作为参数来隐藏特定的行或列。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(dataDir + "book1.xls", FileMode.Open);

// Instantiating a Workbook object
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);

// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.Worksheets[0];

// Hiding the 3rd row of the worksheet
worksheet.Cells.HideRow(2);

// Hiding the 2nd column of the worksheet
worksheet.Cells.HideColumn(1);

// Saving the modified Excel file
workbook.Save(dataDir + "output.out.xls");

// Closing the file stream to free all resources
fstream.Close();

也可以通过将行高或列宽分别设置为 0 来隐藏行或列。

显示行和列

开发人员可以通过调用取消隐藏行和取消隐藏列的方法Cells分别收藏。两种方法都有两个参数：

• 行或列索引 用于显示特定行或列的行或列的索引。
• 行高或列宽 取消隐藏后分配给行或列的行高或列宽。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(dataDir + "book1.xls", FileMode.Open);

// Instantiating a Workbook object
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);

// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.Worksheets[0];

// Unhiding the 3rd row and setting its height to 13.5
worksheet.Cells.UnhideRow(2, 13.5);

// Unhiding the 2nd column and setting its width to 8.5
worksheet.Cells.UnhideColumn(1, 8.5);

// Saving the modified Excel file
workbook.Save(dataDir + "output.xls");

// Closing the file stream to free all resources
fstream.Close();

在使隐藏的列可见时，如果您需要将其恢复到先前分配的宽度或原始宽度，请取消隐藏宽度为负的列。例如：worksheet.Cells.UnhideColumn(5, -1)

隐藏多行多列

开发人员可以通过调用隐藏行和隐藏列的方法Cells分别收藏。这两种方法都将起始行或列索引以及应隐藏的行数或列数作为参数。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Creating a file stream containing the Excel file to be opened
FileStream fstream = new FileStream(dataDir + "book1.xls", FileMode.Open);

// Instantiating a Workbook object
// Opening the Excel file through the file stream
Workbook workbook = new Workbook(fstream);

// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.Worksheets[0];

// Hiding 3,4 and 5 rows in the worksheet
worksheet.Cells.HideRows(2, 3);

// Hiding 2 and 3 columns in the worksheet
worksheet.Cells.HideColumns(1, 2);

// Saving the modified Excel file
workbook.Save(dataDir + "outputxls");

// Closing the file stream to free all resources
fstream.Close();

也可以使用Cells班级'取消隐藏行和取消隐藏列使多行和多列可见的方法。
