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

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。

设置自动格式类型

Microsoft Excel提供多种不同的预设报告格式。Aspose.Cells也支持这些格式选项。要访问它们:

  1. PivotTable.IsAutoFormat设置为true
  2. PivotTableAutoFormatType枚举中分配一个格式选项。
// 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);
// Load a template file
Workbook workbook = new Workbook(dataDir + "Book1.xls");
int pivotindex = 0;
// Get the first worksheet
Worksheet worksheet = workbook.Worksheets[0];
// Accessing the PivotTable
PivotTable pivotTable = worksheet.PivotTables[pivotindex];
// Setting the PivotTable report is automatically formatted
pivotTable.IsAutoFormat = true;
// Setting the PivotTable atuoformat type.
pivotTable.AutoFormatType = Aspose.Cells.Pivot.PivotTableAutoFormatType.Report5;
// Saving the Excel file
workbook.Save(dataDir + "output.xls");

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。

// 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);
// Load a template file
Workbook workbook = new Workbook(dataDir + "Book1.xls");
// Get the first worksheet
Worksheet worksheet = workbook.Worksheets[0];
int pivotindex = 0;
// Accessing the PivotTable
PivotTable pivotTable = worksheet.PivotTables[pivotindex];
// Setting the PivotTable report shows grand totals for rows.
pivotTable.RowGrand = true;
// Setting the PivotTable report shows grand totals for columns.
pivotTable.ColumnGrand = true;
// Setting the PivotTable report displays a custom string in cells that contain null values.
pivotTable.DisplayNullString = true;
pivotTable.NullString = "null";
// Setting the PivotTable report's layout
pivotTable.PageFieldOrder = PrintOrderType.DownThenOver;
// 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格式,而不是使用预设的报告格式,请使用PivotTable.Format()PivotTable.FormatAll()方法。为所需的格式创建一个样式对象,例如:

// 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);
// Load a template file
Workbook workbook = new Workbook(dataDir + "Book1.xls");
// Get the first worksheet
Worksheet worksheet = workbook.Worksheets[0];
var pivot = workbook.Worksheets[0].PivotTables[0];
pivot.PivotTableStyleType = PivotTableStyleType.PivotTableStyleDark1;
Style style = workbook.CreateStyle();
style.Font.Name = "Arial Black";
style.ForegroundColor = Color.Yellow;
style.Pattern = BackgroundType.Solid;
pivot.FormatAll(style);
// Saving the Excel file
workbook.Save(dataDir + "output.xls");

设置数据透视字段格式选项

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。

设置行/列/页字段格式

// 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);
// Load a template file
Workbook workbook = new Workbook(dataDir + "Book1.xls");
// Get the first worksheet
Worksheet worksheet = workbook.Worksheets[0];
int pivotindex = 0;
// Accessing the PivotTable
PivotTable pivotTable = worksheet.PivotTables[pivotindex];
// Setting the PivotTable report shows grand totals for rows.
pivotTable.RowGrand = true;
// Accessing the row fields.
Aspose.Cells.Pivot.PivotFieldCollection pivotFields = pivotTable.RowFields;
// Accessing the first row field in the row fields.
Aspose.Cells.Pivot.PivotField pivotField = pivotFields[0];
// Setting Subtotals.
pivotField.SetSubtotals(Aspose.Cells.Pivot.PivotFieldSubtotalType.Sum, true);
pivotField.SetSubtotals(Aspose.Cells.Pivot.PivotFieldSubtotalType.Count, true);
// Setting autosort options.
// Setting the field auto sort.
pivotField.IsAutoSort = true;
// Setting the field auto sort ascend.
pivotField.IsAscendSort = true;
// Setting the field auto sort using the field itself.
pivotField.AutoSortField = -5;
// Setting autoShow options.
// Setting the field auto show.
pivotField.IsAutoShow = true;
// Setting the field auto show ascend.
pivotField.IsAscendShow = false;
// Setting the auto show using field(data field).
pivotField.AutoShowField = 0;
// Saving the Excel file
workbook.Save(dataDir + "output.xls");

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。

// 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);
// Load a template file
Workbook workbook = new Workbook(dataDir + "Book1.xls");
// Get the first worksheet
Worksheet worksheet = workbook.Worksheets[0];
int pivotindex = 0;
// Accessing the PivotTable
PivotTable pivotTable = worksheet.PivotTables[pivotindex];
// Accessing the data fields.
Aspose.Cells.Pivot.PivotFieldCollection pivotFields = pivotTable.DataFields;
// Accessing the first data field in the data fields.
Aspose.Cells.Pivot.PivotField pivotField = pivotFields[0];
// Setting data display format
pivotField.ShowValuesSetting.CalculationType = PivotFieldDataDisplayFormat.PercentageOf;
// Setting the base field.
pivotField.ShowValuesSetting.BaseFieldIndex = 1;
// Setting the base item.
pivotField.ShowValuesSetting.BaseItemPositionType = Aspose.Cells.Pivot.PivotItemPositionType.Next;
// Setting number format
pivotField.Number = 10;
// Saving the Excel file
workbook.Save(dataDir + "output.xls");

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。

// 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);
// Load a template file
Workbook workbook = new Workbook(dataDir + "Book1.xls");
// Get the first worksheet
Worksheet sheet = workbook.Worksheets[0];
// Get the pivot tables in the sheet
PivotTableCollection pivotTables = sheet.PivotTables;
// Get the first PivotTable
PivotTable pivotTable = pivotTables[0];
// Clear all the data fields
pivotTable.DataFields.Clear();
// Add new data field
pivotTable.AddFieldToArea(PivotFieldType.Data, "Betrag Netto FW");
// Set the refresh data flag on
pivotTable.RefreshDataFlag = false;
// Refresh and calculate the pivot table data
pivotTable.RefreshData();
pivotTable.CalculateData();
// Saving the Excel file
workbook.Save(dataDir + "output.xls");
