在数据透视表中添加过滤器

可能的使用场景

当你创建一个已知数据的数据透视表，并想对数据透视表进行过滤时，你需要学习和使用过滤器。它可以帮助您有效地过滤出您想要的数据。通过使用 Aspose.Cells API，您可以在数据透视表中的字段值上添加过滤器。

在数据透视表中添加过滤器

请参阅以下示例代码。它设置数据并基于它创建数据透视表。然后在数据透视表的行字段上添加过滤器。最后，它将工作簿保存在输出 XLSX格式。执行示例代码后，工作表中添加了一个带有 top10 筛选器的数据透视表。

示例代码

//Instantiating an Workbook object
Workbook workbook = new Workbook();
//Obtaining the reference of the newly added worksheet
Worksheet ws = workbook.Worksheets[0];
Aspose.Cells.Cells cells = ws.Cells;

//Setting the value to the cells
Aspose.Cells.Cell cell = cells["A1"];
cell.PutValue("Fruit");
cell = cells["B1"];
cell.PutValue("Count");

cell = cells["A2"];
cell.PutValue("Apple");
cell = cells["A3"];
cell.PutValue("Mango");
cell = cells["A4"];
cell.PutValue("Blackberry");
cell = cells["A5"];
cell.PutValue("Cherry");
cell = cells["A6"];
cell.PutValue("Guava");
cell = cells["A7"];
cell.PutValue("Carambola");
cell = cells["A8"];
cell.PutValue("Banana");
cell = cells["B2"];
cell.PutValue(5);
cell = cells["B3"];
cell.PutValue(3);
cell = cells["B4"];
cell.PutValue(6);
cell = cells["B5"];
cell.PutValue(4);
cell = cells["B6"];
cell.PutValue(5);
cell = cells["B7"];
cell.PutValue(2);
cell = cells["B8"];
cell.PutValue(20);


//Adding a PivotTable to the worksheet           
int i = ws.PivotTables.Add("=A1:B8", "D10", "PivotTable1");
//Accessing the instance of the newly added PivotTable
PivotTable pivotTable = ws.PivotTables[i];
pivotTable.AddFieldToArea(PivotFieldType.Row, 0);

pivotTable.AddFieldToArea(Aspose.Cells.Pivot.PivotFieldType.Data, "Count");
pivotTable.DataFields[0].Function = ConsolidationFunction.Sum;

PivotField field = pivotTable.RowFields[0];
field.IsAutoSort = true;
field.IsAscendSort = false;
field.AutoSortField = 0;

//Add top10 filter
PivotField filterField = pivotTable.RowFields[0];
filterField.FilterTop10(0, PivotFilterType.Count, false, 5);


pivotTable.RefreshData();
pivotTable.CalculateData();

workbook.Save("filterout.xlsx");
