用C++插入切片器

可能的使用场景

切片器用于快速筛选数据。它可以用于筛选表格或数据透视表中的数据。Microsoft Excel允许通过选择表格或数据透视表，然后点击插入 > 切片器来创建切片器。Aspose.Cells也允许使用Worksheet.Slicers.Add()方法创建切片器。

为数据透视表创建切片器

请参阅以下示例代码。它加载包含数据透视表的示例 Excel 文件。然后基于第一个基本数据透视表字段创建切片器。最后，它以输出 XLSX 和输出 XLSB 格式保存工作簿。以下屏幕截图显示了由 Aspose.Cells 在输出 Excel 文件中创建的切片器。

示例代码

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;
using namespace Aspose::Cells::Pivot;
using namespace Aspose::Cells::Slicers;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Path of input Excel file
    U16String inputFilePath = srcDir + u"sampleCreateSlicerToPivotTable.xlsx";

    // Path of output Excel files
    U16String outputFilePathXlsx = outDir + u"outputCreateSlicerToPivotTable.xlsx";
    U16String outputFilePathXlsb = outDir + u"outputCreateSlicerToPivotTable.xlsb";

    // Load sample Excel file containing pivot table
    Workbook wb(inputFilePath);

    // Access first worksheet
    Worksheet ws = wb.GetWorksheets().Get(0);

    // Access first pivot table inside the worksheet
    PivotTable pt = ws.GetPivotTables().Get(0);

    // Add slicer relating to pivot table with first base field at cell B22
    int idx = ws.GetSlicers().Add(pt, u"B22", pt.GetBaseFields().Get(0));

    // Access the newly added slicer from slicer collection
    Slicer slicer = ws.GetSlicers().Get(idx);

    // Save the workbook in output XLSX format
    wb.Save(outputFilePathXlsx, SaveFormat::Xlsx);

    // Save the workbook in output XLSB format
    wb.Save(outputFilePathXlsb, SaveFormat::Xlsb);

    std::cout << "Slicer created and workbooks saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

为Excel表创建切片器

请查看以下示例代码。它加载包含数据表的sample Excel file，然后基于第一列创建切片器。最后，将工作簿保存为output XLSX格式。

示例代码

#include <iostream>
#include "Aspose.Cells.h"

using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // Source directory path
    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");

    // Output directory path
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    // Load sample Excel file containing a table
    Workbook workbook(srcDir + u"sampleCreateSlicerToExcelTable.xlsx");

    // Access first worksheet
    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    // Access first table inside the worksheet
    ListObject table = worksheet.GetListObjects().Get(0);

    // Add slicer
    int idx = worksheet.GetSlicers().Add(table, 0, u"H5");

    // Save the workbook in output XLSX format
    workbook.Save(outDir + u"outputCreateSlicerToExcelTable.xlsx", SaveFormat::Xlsx);

    std::cout << "Slicer added successfully to the Excel table!" << std::endl;

    Aspose::Cells::Cleanup();
}
