格式化数据透视表

数据透视表外观

如何创建数据透视表介绍了如何创建简单的数据透视表。本文描述了如何通过设置各种属性来自定义数据透视表的外观:

  • 数据透视表格式选项
  • 数据透视字段格式选项
  • 数据字段格式选项

如何设置数据透视表格式选项

PivotTable类控制整体数据透视表,可以以多种方式进行格式设置。

如何设置自动格式类型

Microsoft Excel提供许多不同的预设报告格式,Aspose.Cells for Python via .NET也支持这些格式选项。要访问它们:

  1. PivotTable.is_auto_format设置为true
  2. PivotTableAutoFormatType枚举中分配一个格式选项。
from aspose.cells import Workbook
from aspose.cells.pivot import PivotTableAutoFormatType
# 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(".")
# Load a template file
workbook = Workbook(dataDir + "Book1.xls")
pivotindex = 0
# Get the first worksheet
worksheet = workbook.worksheets[0]
# Accessing the PivotTable
pivotTable = worksheet.pivot_tables[pivotindex]
# Setting the PivotTable report is automatically formatted
pivotTable.is_auto_format = True
# Setting the PivotTable atuoformat type.
pivotTable.auto_format_type = PivotTableAutoFormatType.REPORT5
# Saving the Excel file
workbook.save(dataDir + "output.xls")

如何设置格式选项

下面的代码示例演示了如何格式化数据透视表以显示行和列的总计,以及如何设置报告的字段顺序。它还显示了如何为空值设置自定义字符串。

from aspose.cells import PrintOrderType, 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(".")
# Load a template file
workbook = Workbook(dataDir + "Book1.xls")
# Get the first worksheet
worksheet = workbook.worksheets[0]
pivotindex = 0
# Accessing the PivotTable
pivotTable = worksheet.pivot_tables[pivotindex]
# Setting the PivotTable report shows grand totals for rows.
pivotTable.row_grand = True
# Setting the PivotTable report shows grand totals for columns.
pivotTable.column_grand = True
# Setting the PivotTable report displays a custom string in cells that contain null values.
pivotTable.display_null_string = True
pivotTable.null_string = "null"
# Setting the PivotTable report's layout
pivotTable.page_field_order = PrintOrderType.DOWN_THEN_OVER
# Saving the Excel file
workbook.save(dataDir + "output.xls")

手动设置外观和感觉格式

要手动设置数据透视表报告的外观和感觉,而不是使用预设的报告格式,请使用PivotTable.format_all(style)PivotTable.format(row, column, style)方法。为所需的格式创建样式对象,例如:

from aspose.cells import BackgroundType, Workbook
from aspose.cells.pivot import PivotTableStyleType
from aspose.pydrawing import Color
# 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(".")
# Load a template file
workbook = Workbook(dataDir + "Book1.xls")
# Get the first worksheet
worksheet = workbook.worksheets[0]
pivot = workbook.worksheets[0].pivot_tables[0]
pivot.pivot_table_style_type = PivotTableStyleType.PIVOT_TABLE_STYLE_DARK1
style = workbook.create_style()
style.font.name = "Arial Black"
style.foreground_color = Color.yellow
style.pattern = BackgroundType.SOLID
pivot.format_all(style)
# Saving the Excel file
workbook.save(dataDir + "output.xls")

如何设置数据透视表字段格式选项

PivotField类表示数据透视表中的字段,并可以以多种方式进行格式设置。下面的代码示例演示了如何:

  • 访问行字段。
  • 设置合计。
  • 设置自动排序。
  • 设置自动显示。

如何设置行/列/页面字段格式

from aspose.cells import Workbook
from aspose.cells.pivot import PivotFieldSubtotalType
# 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(".")
# Load a template file
workbook = Workbook(dataDir + "Book1.xls")
# Get the first worksheet
worksheet = workbook.worksheets[0]
pivotindex = 0
# Accessing the PivotTable
pivotTable = worksheet.pivot_tables[pivotindex]
# Setting the PivotTable report shows grand totals for rows.
pivotTable.row_grand = True
# Accessing the row fields.
pivotFields = pivotTable.row_fields
# Accessing the first row field in the row fields.
pivotField = pivotFields[0]
# Setting Subtotals.
pivotField.set_subtotals(PivotFieldSubtotalType.SUM, True)
pivotField.set_subtotals(PivotFieldSubtotalType.COUNT, True)
# Setting autosort options.
# Setting the field auto sort.
pivotField.is_auto_sort = True
# Setting the field auto sort ascend.
pivotField.is_ascend_sort = True
# Setting the field auto sort using the field itself.
pivotField.auto_sort_field = -5
# Setting autoShow options.
# Setting the field auto show.
pivotField.is_auto_show = True
# Setting the field auto show ascend.
pivotField.is_ascend_show = False
# Setting the auto show using field(data field).
pivotField.auto_show_field = 0
# Saving the Excel file
workbook.save(dataDir + "output.xls")

如何设置数据字段格式

以下代码示例显示如何设置数据字段的显示格式和数字格式。

from aspose.cells import Workbook
from aspose.cells.pivot import PivotFieldDataDisplayFormat, PivotItemPosition
# 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(".")
# Load a template file
workbook = Workbook(dataDir + "Book1.xls")
# Get the first worksheet
worksheet = workbook.worksheets[0]
pivotindex = 0
# Accessing the PivotTable
pivotTable = worksheet.pivot_tables[pivotindex]
# Accessing the data fields.
pivotFields = pivotTable.data_fields
# Accessing the first data field in the data fields.
pivotField = pivotFields[0]
# Setting data display format
pivotField.data_display_format = PivotFieldDataDisplayFormat.PERCENTAGE_OF
# Setting the base field.
pivotField.base_field_index = 1
# Setting the base item.
pivotField.base_item_position = PivotItemPosition.NEXT
# Setting number format
pivotField.number = 10
# Saving the Excel file
workbook.save(dataDir + "output.xls")

如何清除数据透视字段

PivotFieldCollection 有一个名为 clear() 的方法,允许您清除数据透视字段。当您想要清除区域中的所有数据透视字段时(例如页、列、行或数据),请使用它。 以下代码示例显示如何清除数据区域中的所有数据透视字段。

from aspose.cells import Workbook
from aspose.cells.pivot import PivotFieldType
# 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(".")
# Load a template file
workbook = Workbook(dataDir + "Book1.xls")
# Get the first worksheet
sheet = workbook.worksheets[0]
# Get the pivot tables in the sheet
pivotTables = sheet.pivot_tables
# Get the first PivotTable
pivotTable = pivotTables[0]
# Clear all the data fields
pivotTable.data_fields.clear()
# Add new data field
pivotTable.add_field_to_area(PivotFieldType.DATA, "Betrag Netto FW")
# Set the refresh data flag on
pivotTable.refresh_data_flag = False
# Refresh and calculate the pivot table data
pivotTable.refresh_data()
pivotTable.calculate_data()
# Saving the Excel file
workbook.save(dataDir + "output.xls")
