格式化数据透视表
数据透视表外观
《如何创建透视表》(/cells/zh/java/create-pivot-table/)展示了如何创建一个简单的透视表。这篇文章进一步讨论了如何通过设置属性自定义透视表的外观。
设置数据透视表格式选项
PivotTable 类允许您为透视表设置各种格式选项。
设置自动格式和透视表样式类型
接下来的代码示例说明了如何使用 AutoFormatType 属性和 PivotTableStyleType 属性设置自动格式类型和透视表样式类型。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getSharedDataDir(SetAutoFormatandPivotTableStyleTypes.class) + "PivotTables/"; | |
// Load a template file | |
Workbook workbook = new Workbook(dataDir + "PivotTable.xls"); | |
int pivotindex = 0; | |
// Get the first worksheet | |
Worksheet worksheet = workbook.getWorksheets().get(pivotindex); | |
// Accessing the PivotTable | |
PivotTable pivotTable = worksheet.getPivotTables().get(pivotindex); | |
//Setting the PivotTable report is automatically formatted for Excel 2003 formats | |
pivotTable.setAutoFormat(true); | |
//Setting the PivotTable atuoformat type. | |
pivotTable.setAutoFormatType(PivotTableAutoFormatType.CLASSIC); | |
//Setting the PivotTable's Styles for Excel 2007/2010 formats e.g XLSX. | |
pivotTable.setPivotTableStyleType(PivotTableStyleType.PIVOT_TABLE_STYLE_LIGHT_1); |
设置格式选项
接下来的代码示例说明了如何为透视表报告设置多项格式选项,包括为行和列添加总计。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getSharedDataDir(SettingFormatOptions.class) + "PivotTables/"; | |
// Load a template file | |
Workbook workbook = new Workbook(dataDir + "PivotTable.xls"); | |
// Get the first worksheet | |
Worksheet worksheet = workbook.getWorksheets().get(0); | |
PivotTable pivotTable = worksheet.getPivotTables().get(0); | |
// Dragging the third field to the data area. | |
pivotTable.addFieldToArea(PivotFieldType.DATA, 2); | |
// Show grand totals for rows. | |
pivotTable.setRowGrand(true); | |
// Show grand totals for columns. | |
pivotTable.setColumnGrand(true); | |
// Display a custom string in cells that contain null values. | |
pivotTable.setDisplayNullString(true); | |
pivotTable.setNullString("null"); | |
// Setting the layout | |
pivotTable.setPageFieldOrder(PrintOrderType.DOWN_THEN_OVER); |
设置透视字段格式选项
除了控制整个数据透视表的格式外,Aspose.Cells for Java 还允许对行字段、列字段和页面字段的格式进行精细控制。
设置行、列和页面字段格式
接下来的代码示例显示了如何访问行字段,访问特定行,设置小计,应用自动排序,并使用自动显示选项。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getSharedDataDir(SetRowColumnPageFieldsFormat.class) + "PivotTables/"; | |
// Load a template file | |
Workbook workbook = new Workbook(dataDir + "PivotTable.xls"); | |
// Get the first worksheet | |
Worksheet worksheet = workbook.getWorksheets().get(0); | |
PivotTable pivotTable = worksheet.getPivotTables().get(0); | |
// Accessing the row fields. | |
PivotFieldCollection pivotFields = pivotTable.getRowFields(); | |
// Accessing the first row field in the row fields. | |
PivotField pivotField = pivotFields.get(0); | |
// Setting Subtotals. | |
pivotField.setSubtotals(PivotFieldSubtotalType.SUM, true); | |
pivotField.setSubtotals(PivotFieldSubtotalType.COUNT, true); | |
// Setting autosort options. Setting the field auto sort. | |
pivotField.setAutoSort(true); | |
// Setting the field auto sort ascend. | |
pivotField.setAscendSort(true); | |
// Setting the field auto sort using the field itself. | |
pivotField.setAutoSortField(-1); | |
// Setting autoShow options. Setting the field auto show. | |
pivotField.setAutoShow(true); | |
// Setting the field auto show ascend. | |
pivotField.setAscendShow(false); | |
// Setting the auto show using field(data field). | |
pivotField.setAutoShowField(0); |
设置数据字段格式
下面的代码行演示了如何格式化数据字段。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getSharedDataDir(SettingDataFieldFormat.class) + "PivotTables/"; | |
// Load a template file | |
Workbook workbook = new Workbook(dataDir + "PivotTable.xls"); | |
// Get the first worksheet | |
Worksheet worksheet = workbook.getWorksheets().get(0); | |
PivotTable pivotTable = worksheet.getPivotTables().get(0); | |
// Accessing the data fields. | |
PivotFieldCollection pivotFields = pivotTable.getDataFields(); | |
// Accessing the first data field in the data fields. | |
PivotField pivotField = pivotFields.get(0); | |
// Setting data display format | |
pivotField.setDataDisplayFormat(PivotFieldDataDisplayFormat.PERCENTAGE_OF); | |
// Setting the base field. | |
pivotField.setBaseFieldIndex(1); | |
// Setting the base item. | |
pivotField.setBaseItemPosition(PivotItemPosition.NEXT); | |
// Setting number format | |
pivotField.setNumber(10); |
修改透视表的快速样式
接下来的代码示例展示了如何修改应用于透视表的快速样式。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getSharedDataDir(ModifyPivotTableQuickStyle.class) + "PivotTables/"; | |
// Open the template file containing the pivot table. | |
Workbook wb = new Workbook(dataDir + "sample1.xlsx"); | |
// Add Pivot Table style | |
Style style1 = wb.createStyle(); | |
com.aspose.cells.Font font1 = style1.getFont(); | |
font1.setColor(Color.getRed()); | |
Style style2 = wb.createStyle(); | |
com.aspose.cells.Font font2 = style2.getFont(); | |
font2.setColor(Color.getBlue()); | |
int i = wb.getWorksheets().getTableStyles().addPivotTableStyle("tt"); | |
// Get and Set the table style for different categories | |
TableStyle ts = wb.getWorksheets().getTableStyles().get(i); | |
int index = ts.getTableStyleElements().add(TableStyleElementType.FIRST_COLUMN); | |
TableStyleElement e = ts.getTableStyleElements().get(index); | |
e.setElementStyle(style1); | |
index = ts.getTableStyleElements().add(TableStyleElementType.GRAND_TOTAL_ROW); | |
e = ts.getTableStyleElements().get(index); | |
e.setElementStyle(style2); | |
// Set Pivot Table style name | |
PivotTable pt = wb.getWorksheets().get(0).getPivotTables().get(0); | |
pt.setPivotTableStyleName("tt"); | |
// Save the file. | |
wb.save(dataDir + "ModifyPivotTableQuickStyle_out.xlsx"); |
清除数据透视字段
PivotFieldCollection有一个名为clear()的方法用于清除数据透视表字段。在清除页面、列、行或数据等区域的数据透视表字段时使用它。 下面的代码示例显示了如何清除数据区域中的所有透视字段。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getSharedDataDir(ClearPivotFields.class) + "PivotTables/"; | |
// Load a template file | |
Workbook workbook = new Workbook(dataDir + "PivotTable.xls"); | |
// Get the first worksheet | |
Worksheet sheet = workbook.getWorksheets().get(0); | |
// Get the pivot tables in the sheet | |
PivotTableCollection pivotTables = sheet.getPivotTables(); | |
// Get the first PivotTable | |
PivotTable pivotTable = pivotTables.get(0); | |
// Clear all the data fields | |
pivotTable.getDataFields().clear(); | |
// Add new data field | |
pivotTable.addFieldToArea(PivotFieldType.DATA, "Betrag Netto FW"); | |
// Set the refresh data flag on | |
pivotTable.setRefreshDataFlag(false); | |
// Refresh and calculate the pivot table data | |
pivotTable.refreshData(); | |
pivotTable.calculateData(); | |
// Save the Excel file | |
workbook.save(dataDir + "ClearPivotFields_out.xlsx"); |
合并功能
应用合并功能到数据字段的数据透视表
Aspose.Cells可用于应用合并功能到数据透视表的数据字段(或值字段)。在Microsoft Excel中,您可以右键单击值字段,然后选择值字段设置…选项,然后选择汇总方式选项卡。从那里,您可以选择任何您喜欢的合并功能,如求和、计数、平均值、最大值、最小值、乘积、去重计数等。
Aspose.Cells提供ConsolidationFunction枚举以支持以下合并功能。
- ConsolidationFunction.AVERAGE
- ConsolidationFunction.COUNT
- ConsolidationFunction.COUNT_NUMS
- ConsolidationFunction.DISTINCT_COUNT
- ConsolidationFunction.MAX
- ConsolidationFunction.MIN
- ConsolidationFunction.PRODUCT
- ConsolidationFunction.STD_DEV
- ConsolidationFunction.STD_DEVP
- ConsolidationFunction.SUM
- ConsolidationFunction.VAR
- ConsolidationFunction.VARP
以下代码将平均值合并功能应用于第一个数据字段(或值字段),并将去重计数合并功能应用于第二个数据字段(或值字段)。
// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java | |
// The path to the documents directory. | |
String dataDir = Utils.getSharedDataDir(ConsolidationFunctions.class) + "PivotTables/"; | |
// Create workbook from source excel file | |
Workbook workbook = new Workbook(dataDir + "sample1.xlsx"); | |
// Access the first worksheet of the workbook | |
Worksheet worksheet = workbook.getWorksheets().get(0); | |
// Access the first pivot table of the worksheet | |
PivotTable pivotTable = worksheet.getPivotTables().get(0); | |
// Apply Average consolidation function to first data field | |
pivotTable.getDataFields().get(0).setFunction(ConsolidationFunction.AVERAGE); | |
// Apply DistinctCount consolidation function to second data field | |
pivotTable.getDataFields().get(1).setFunction(ConsolidationFunction.DISTINCT_COUNT); | |
// Calculate the data to make changes affect | |
pivotTable.calculateData(); | |
// Save the workbook | |
workbook.save(dataDir + "ConsolidationFunctions_out.xlsx"); |
