行和列的分组和取消分组

介绍

在 Microsoft Excel 文件中，您可以创建一个数据大纲，以便通过单击鼠标来显示和隐藏不同级别的细节。

单击大纲符号1、2、3、+和- 快速显示工作表中仅提供摘要或标题部分的行或列，或者您可使用符号查看摘要或标题下的详细信息，如下图所示:

分组行和列

行和列的分组管理

Aspose.Cells for Python via .NET提供了一个代表Microsoft Excel文件的类Workbook。Workbook类包含一个WorksheetCollection，允许访问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行或列的方法，以下将更详细地讨论其中的一些。

如何对行和列进行分组

通过调用Cells集合的group_rows和group_columns方法，可以对行或列进行分组。这两种方法都带有以下参数:

• 第一个行/列索引，即组中的第一行或列。
• 最后一个行/列索引，即组中的最后一行或列。
• 是否隐藏，一个布尔参数，指定是否在分组后隐藏行/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")
#  Opening the Excel file through the file stream
workbook = Workbook(fstream)
#  Accessing the first worksheet in the Excel file
worksheet = workbook.worksheets[0]
#  Grouping first six rows (from 0 to 5) and making them hidden by passing true
worksheet.cells.group_rows(0, 5, True)
#  Grouping first three columns (from 0 to 2) and making them hidden by passing true
worksheet.cells.group_columns(0, 2, True)
#  Saving the modified Excel file
workbook.save(dataDir + "output.xls")
#  Closing the file stream to free all resources
fstream.close()

分组设置

Microsoft Excel 允许您配置用于显示的分组设置：

• 详细信息下面的摘要行。
• 详细信息右侧的摘要列。

开发者可以使用Worksheet类的outline属性配置这些组设置。

如何将汇总行放置在细节下方

可以通过将Outline类的summary_row_below属性设置为true或false来控制是否在详细信息下方显示摘要行。

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(".")
workbook = Workbook(dataDir + "sample.xlsx")
worksheet = workbook.worksheets[0]
#  Grouping first six rows and first three columns
worksheet.cells.group_rows(0, 5, True)
worksheet.cells.group_columns(0, 2, True)
#  Setting SummaryRowBelow property to false
worksheet.outline.summary_row_below = False
#  Saving the modified Excel file
workbook.save(dataDir + "output.xls")

如何将汇总列放置在细节右侧

开发者还可以通过将Outline类的summary_column_right属性设置为true或false来控制是否在详细信息右侧显示摘要列。

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(".")
workbook = Workbook(dataDir + "sample.xlsx")
worksheet = workbook.worksheets[0]
#  Grouping first six rows and first three columns
worksheet.cells.group_rows(0, 5, True)
worksheet.cells.group_columns(0, 2, True)
worksheet.outline.summary_column_right = True
#  Saving the modified Excel file
workbook.save(dataDir + "output.xls")

如何取消分组行和列

要取消任何已分组的行或列，调用Cells集合的ungroup_rows和ungroup_columns方法。这两个方法都带有两个参数:

• 第一个行或列索引，即要取消分组的第一行/列。
• 最后一个行或列索引，即要取消分组的最后一行/列。

ungroup_rows有一个额外的重载，它带有一个布尔型第三个参数。将其设置为true会移除所有分组信息。否则，只有外部的组信息会被移除。

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]
#  Ungrouping first six rows (from 0 to 5)
worksheet.cells.ungroup_rows(0, 5)
#  Ungrouping first three columns (from 0 to 2)
worksheet.cells.ungroup_columns(0, 2)
#  Saving the modified Excel file
workbook.save(dataDir + "output.xls")
#  Closing the file stream to free all resources
fstream.close()
