隐藏和显示行和列

有时，在工作表中隐藏某些行或列并稍后再显示它们是有意义的。微软 Excel 提供了这一功能，Aspose.Cells for Python via .NET 也有。

控制行和列的可见性

Aspose.Cells for Python via .NET 提供了一个类，Workbook，代表一个微软 Excel 文件。Workbook 类包含一个 WorksheetCollection，让开发人员可以访问 Excel 文件中的每个工作表。工作表由 Worksheet 类表示。Worksheet 类提供了一个 cells 集合，代表工作表中的所有单元格。cells 集合提供了几种管理工作表中行或列的方法。以下是其中一些讨论的方法。

如何隐藏行和列

开发人员可以通过调用cells集合的hide_row和hide_column方法，分别隐藏行或列。两种方法都以行索引或列索引作为参数，以隐藏特定的行或列。

from aspose.cells import Workbook

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Creating a file stream containing the Excel file to be opened
fstream = open(dataDir + "book1.xls", "rb")
#  Instantiating a Workbook object
#  Opening the Excel file through the file stream
workbook = Workbook(fstream)
#  Accessing the first worksheet in the Excel file
worksheet = workbook.worksheets[0]
#  Hiding the 3rd row of the worksheet
worksheet.cells.hide_row(2)
#  Hiding the 2nd column of the worksheet
worksheet.cells.hide_column(1)
#  Saving the modified Excel file
workbook.save(dataDir + "output.out.xls")
#  Closing the file stream to free all resources
fstream.close()

还可以通过将行高或列宽设置为0来隐藏行或列。

如何显示行和列

开发人员可以通过调用cells集合的unhide_row和unhide_column方法，分别显示任何隐藏的行或列。两种方法都需要两个参数：

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

from aspose.cells import Workbook

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Creating a file stream containing the Excel file to be opened
fstream = open(dataDir + "book1.xls", "rb")
#  Instantiating a Workbook object
#  Opening the Excel file through the file stream
workbook = Workbook(fstream)
#  Accessing the first worksheet in the Excel file
worksheet = workbook.worksheets[0]
#  Unhiding the 3rd row and setting its height to 13.5
worksheet.cells.unhide_row(2, 13.5)
#  Unhiding the 2nd column and setting its width to 8.5
worksheet.cells.unhide_column(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，如果需要恢复其先前分配的宽度或其原始宽度，请使用负宽度取消隐藏列。例如：worksheet.Cells.UnhideColumn(5, -1)

如何隐藏多个行和列

开发人员可以通过调用cells集合的hide_rows和hide_columns方法，分别一次隐藏多行或列。两种方法都需要起始行或列索引和应该隐藏的行数或列数作为参数。

from aspose.cells import Workbook

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Creating a file stream containing the Excel file to be opened
fstream = open(dataDir + "book1.xls", "rb")
#  Instantiating a Workbook object
#  Opening the Excel file through the file stream
workbook = Workbook(fstream)
#  Accessing the first worksheet in the Excel file
worksheet = workbook.worksheets[0]
#  Hiding 3,4 and 5 rows in the worksheet
worksheet.cells.hide_rows(2, 3)
#  Hiding 2 and 3 columns in the worksheet
worksheet.cells.hide_columns(1, 2)
#  Saving the modified Excel file
workbook.save(dataDir + "outputxls")
#  Closing the file stream to free all resources
fstream.close()

还可以使用Cells类的unhide_rows和unhide_columns方法来显示多行和列。
