C++を使った名前付き範囲の数式設定

名前付き範囲の式の設定

Excelアプリケーションと同様に、Aspose.Cells APIは、そのGetRefersTo()プロパティを使用して名前付き範囲に対する数式を指定する機能を提供します。この機能にはさまざまなユースケースがあります。以下にいくつか例を挙げます。

名前付き範囲に簡単な式を設定する

簡単な式は、同じワークシート（または異なるワークシート）内の別のセルへの参照である場合があります。次の例は、新しいスプレッドシートで名前付き範囲を作成し、その参照先を別のセルに設定します。

#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\\");

    // Create an instance of Workbook
    Workbook book;

    // Get the WorksheetCollection
    WorksheetCollection worksheets = book.GetWorksheets();

    // Add a new Named Range with name "NewNamedRange"
    int index = worksheets.GetNames().Add(u"NewNamedRange");

    // Access the newly created Named Range
    Name name = worksheets.GetNames().Get(index);

    // Set RefersTo property of the Named Range to a formula. Formula references another cell in the same worksheet
    name.SetRefersTo(u"=Sheet1!$A$3");

    // Set the formula in the cell A1 to the newly created Named Range
    worksheets.Get(0).GetCells().Get(u"A1").SetFormula(u"NewNamedRange");

    // Insert the value in cell A3 which is being referenced in the Named Range
    worksheets.Get(0).GetCells().Get(u"A3").PutValue(u"This is the value of A3");

    // Calculate formulas
    book.CalculateFormula();

    // Save the result in XLSX format
    book.Save(outDir + u"output_out.xlsx");

    std::cout << "Named range created and formula calculated successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

名前付き範囲に複雑な式を設定する

複雑な式は、動的な範囲や異なるワークシートの複数のセルにまたがる式など、さまざまなものになります。次の例は、INDEX 関数を使用して、リスト内の位置に基づいて値を取得する動的な範囲を作成します。

#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\\");

    // Create an instance of Workbook
    Workbook book;

    // Get the WorksheetCollection
    WorksheetCollection worksheets = book.GetWorksheets();

    // Add a new Named Range with name "data"
    int index = worksheets.GetNames().Add(u"data");

    // Access the newly created Named Range from the collection
    Name data = worksheets.GetNames().Get(index);

    // Set RefersTo property of the Named Range to a cell range in same worksheet
    data.SetRefersTo(u"=Sheet1!$A$1:$A$10");

    // Add another Named Range with name "range"
    index = worksheets.GetNames().Add(u"range");

    // Access the newly created Named Range from the collection
    Name range = worksheets.GetNames().Get(index);

    // Set RefersTo property to a formula using the Named Range data
    range.SetRefersTo(u"=INDEX(data,Sheet1!$A$1,1):INDEX(data,Sheet1!$A$1,9)");

    // Save the workbook
    book.Save(outDir + u"output_out.xlsx");

    std::cout << "Named ranges created and workbook saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

異なるワークシートの2つのセルから値を合計する名前付き範囲を使用するもう1つの例がこちら

#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\\");

    // Create an instance of Workbook
    Workbook book;

    // Get the WorksheetCollection
    WorksheetCollection worksheets = book.GetWorksheets();

    // Insert some data in cell A1 of Sheet1
    worksheets.Get(u"Sheet1").GetCells().Get(u"A1").PutValue(10);

    // Add a new Worksheet and insert a value to cell A1
    worksheets.Get(worksheets.Add()).GetCells().Get(u"A1").PutValue(10);

    // Add a new Named Range with name "range"
    int index = worksheets.GetNames().Add(u"range");

    // Access the newly created Named Range from the collection
    Name range = worksheets.GetNames().Get(index);

    // Set RefersTo property of the Named Range to a SUM function
    range.SetRefersTo(u"=SUM(Sheet1!$A$1,Sheet2!$A$1)");

    // Insert the Named Range as formula to 3rd worksheet
    worksheets.Get(worksheets.Add()).GetCells().Get(u"A1").SetFormula(u"range");

    // Calculate formulas
    book.CalculateFormula();

    // Save the result in XLSX format
    book.Save(outDir + u"output_out.xlsx");

    std::cout << "Output file saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}
