Modifier, mettre en forme et modifier les plages nommées avec C++

Format des plages

Définir la couleur d’arrière-plan et les attributs de police à une plage nommée

Pour appliquer le formatage, définissez un objet Style pour spécifier les paramètres de style et appliquez-le à l’objet Range.

L’exemple suivant montre comment définir la couleur de remplissage pleine (couleur d’ombrage) avec des paramètres de police à une plage.

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

using namespace Aspose::Cells;

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

    U16String srcDir(u"..\\Data\\01_SourceDirectory\\");
    U16String outDir(u"..\\Data\\02_OutputDirectory\\");

    Workbook workbook;
    Worksheet WS = workbook.GetWorksheets().Get(0);
    Range range = WS.GetCells().CreateRange(1, 1, 1, 18);

    range.SetName(u"MyRange");

    Style stl = workbook.CreateStyle();

    stl.GetFont().SetName(u"Arial");
    stl.GetFont().SetIsBold(true);
    stl.GetFont().SetColor(Color::Red());
    stl.SetForegroundColor(Color::Yellow());
    stl.SetPattern(BackgroundType::Solid);

    StyleFlag flg;
    flg.SetFont(true);
    flg.SetCellShading(true);

    range.ApplyStyle(stl, flg);

    workbook.Save(outDir + u"rangestyles.out.xls");

    Aspose::Cells::Cleanup();
}

Ajout de bordures à une plage nommée

Il est possible d’ajouter des bordures à une plage de cellules au lieu d’une seule cellule. L’objet Range fournit une méthode SetOutlineBorder qui prend les paramètres suivants pour ajouter une bordure à la plage de cellules:

• Type de bordure, le type de bordure, sélectionné de l’énumération BorderType.
• Style de ligne, le style de ligne, sélectionné de l’énumération CellBorderType.
• Couleur, la couleur de la ligne, sélectionnée dans l’énumération de couleur.

L’exemple suivant montre comment définir une bordure de contour à une plage.

#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\\");

    // Instantiating a Workbook object
    Workbook workbook;

    // Clears the worksheets
    workbook.GetWorksheets().Clear();

    // Adding a new worksheet to the Workbook object
    workbook.GetWorksheets().Add();

    // Obtaining the reference of the newly added worksheet by passing its sheet index
    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    // Accessing the "A1" cell from the worksheet
    Cell cell = worksheet.GetCells().Get(u"A1");

    // Adding some value to the "A1" cell
    cell.PutValue(u"Hello World From Aspose");

    // Creating a range of cells starting from "A1" cell to 3rd column in a row
    Range range = worksheet.GetCells().CreateRange(0, 0, 1, 3);

    // Adding a thick top border with blue line
    range.SetOutlineBorder(BorderType::TopBorder, CellBorderType::Thick, Color::Blue());

    // Adding a thick bottom border with blue line
    range.SetOutlineBorder(BorderType::BottomBorder, CellBorderType::Thick, Color::Blue());

    // Adding a thick left border with blue line
    range.SetOutlineBorder(BorderType::LeftBorder, CellBorderType::Thick, Color::Blue());

    // Adding a thick right border with blue line
    range.SetOutlineBorder(BorderType::RightBorder, CellBorderType::Thick, Color::Blue());

    // Saving the Excel file
    workbook.Save(outDir + u"book1.out.xls");

    std::cout << "File saved successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

L’exemple suivant montre comment définir des bordures autour de chaque cellule de la plage.

#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\\");

    // Instantiate a new Workbook
    Workbook workbook;

    // Access the cells in the first worksheet
    Cells cells = workbook.GetWorksheets().Get(0).GetCells();

    // Create a range of cells
    Range range = cells.CreateRange(u"A6", u"P216");

    // Create the style adding to the style collection
    Style stl = workbook.CreateStyle();

    // Specify the font settings
    stl.GetFont().SetName(u"Arial");
    stl.GetFont().SetIsBold(true);
    stl.GetFont().SetColor(Color::Blue());

    // Set the borders
    stl.GetBorders().Get(BorderType::TopBorder).SetLineStyle(CellBorderType::Thin);
    stl.GetBorders().Get(BorderType::TopBorder).SetColor(Color::Blue());
    stl.GetBorders().Get(BorderType::LeftBorder).SetLineStyle(CellBorderType::Thin);
    stl.GetBorders().Get(BorderType::LeftBorder).SetColor(Color::Blue());
    stl.GetBorders().Get(BorderType::BottomBorder).SetLineStyle(CellBorderType::Thin);
    stl.GetBorders().Get(BorderType::BottomBorder).SetColor(Color::Blue());
    stl.GetBorders().Get(BorderType::RightBorder).SetLineStyle(CellBorderType::Thin);
    stl.GetBorders().Get(BorderType::RightBorder).SetColor(Color::Blue());

    // Create StyleFlag object
    StyleFlag flg;

    // Make the corresponding formatting attributes ON
    flg.SetFont(true);
    flg.SetBorders(true);

    // Apply the style with format settings to the range
    range.ApplyStyle(stl, flg);

    // Save the excel file
    workbook.Save(outDir + u"output.xls");

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

    Aspose::Cells::Cleanup();
}

Renommer une plage nommée

Aspose.Cells vous permet de renommer une plage nommée selon vos besoins. Vous pouvez obtenir la plage nommée et la renommer en utilisant l’attribut Name.GetText(). L’exemple suivant montre comment renommer une plage nommée.

#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\\");

    // Path of input Excel file
    U16String inputFilePath = srcDir + u"book1.xls";

    // Path of output Excel file
    U16String outputFilePath = outDir + u"RenamingRange.out.xlsx";

    // Create workbook
    Workbook workbook(inputFilePath);

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

    // Get the Cells of the sheet
    Cells cells = sheet.GetCells();

    // Get the named range "TestRange"
    Name name = workbook.GetWorksheets().GetNames().Get(u"TestRange");

    // Rename it
    name.SetText(u"NewRange");

    // Save the Excel file
    workbook.Save(outputFilePath);

    std::cout << "Range renamed successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

Union des plages

Aspose.Cells fournit Range.UnionRang méthode pour prendre l’union de plages, la méthode retourne un objet std::vector. L’exemple suivant montre comment faire l’union de plages.

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

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

    U16String srcDir(u"../Data/01_SourceDirectory/");
    U16String outDir(u"../Data/02_OutputDirectory/");

    Workbook workbook(srcDir + u"book1.xls");

    Vector<Range> ranges = workbook.GetWorksheets().GetNamedRanges();

    Style style = workbook.CreateStyle();
    style.SetForegroundColor(Color::Yellow());
    style.SetPattern(BackgroundType::Solid);

    StyleFlag flag;
    flag.SetCellShading(true);

    Vector<Range> unionParams{ ranges[1] };
    UnionRange unionResult = ranges[0].UnionRanges(unionParams);
    Vector<Range> al = unionResult.GetRanges();

    for (int i = 0; i < al.GetLength(); i++)
    {
        Range rng = al[i];
        rng.ApplyStyle(style, flag);
    }

    workbook.Save(outDir + u"rngUnion.out.xls");

    std::cout << "Style applied to union ranges successfully." << std::endl;

    Aspose::Cells::Cleanup();
}

Intersection des plages

Aspose.Cells fournit la méthode Range.Intersect pour intersecter deux plages. La méthode renvoie un objet Range. Pour vérifier si une plage intersecte une autre plage, utilisez la méthode Range.Intersect qui renvoie une valeur booléenne. L’exemple suivant montre comment intersecter les plages.

#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\\");

    // Path of input excel file
    U16String inputFilePath = srcDir + u"book1.xls";

    // Path of output excel file
    U16String outputFilePath = outDir + u"rngIntersection.out.xls";

    // Create workbook
    Workbook workbook(inputFilePath);

    // Get the named ranges
    Vector<Range> ranges = workbook.GetWorksheets().GetNamedRanges();

    // Check whether the first range intersects the second range
    bool isIntersect = ranges[0].IsIntersect(ranges[1]);

    // Create a style object
    Style style = workbook.CreateStyle();

    // Set the shading color with solid pattern type
    style.SetForegroundColor(Color::Yellow());
    style.SetPattern(BackgroundType::Solid);

    // Create a styleflag object
    StyleFlag flag;

    // Apply the cell shading
    flag.SetCellShading(true);

    // If first range intersects second range
    if (isIntersect)
    {
        // Create a range by getting the intersection
        Range intersection = ranges[0].Intersect(ranges[1]);

        // Name the range
        intersection.SetName(u"Intersection");

        // Apply the style to the range
        intersection.ApplyStyle(style, flag);
    }

    // Save the excel file
    workbook.Save(outputFilePath);

    std::cout << "Range intersection processed successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

Fusionner les cellules dans la plage nommée

Aspose.Cells fournit la méthode Range.Merge() pour fusionner les cellules dans la plage. L’exemple suivant montre comment fusionner les cellules individuelles d’une plage nommée.

#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\\");

    // Instantiate a new Workbook
    Workbook wb1;

    // Get the first worksheet in the workbook
    Worksheet worksheet1 = wb1.GetWorksheets().Get(0);

    // Create a range
    Range mrange = worksheet1.GetCells().CreateRange(u"A18", u"J18");

    // Name the range
    mrange.SetName(u"Details");

    // Merge the cells of the range
    mrange.Merge();

    // Get the range by name
    Range range1 = wb1.GetWorksheets().GetRangeByName(u"Details");

    // Define a style object
    Style style = wb1.CreateStyle();

    // Set the alignment
    style.SetHorizontalAlignment(TextAlignmentType::Center);

    // Create a StyleFlag object
    StyleFlag flag;
    // Make the relative style attribute ON
    flag.SetHorizontalAlignment(true);

    // Apply the style to the range
    range1.ApplyStyle(style, flag);

    // Input data into range
    range1.Get(0, 0).PutValue(u"Aspose");

    // Save the excel file
    wb1.Save(outDir + u"mergingrange.out.xls");

    std::cout << "Range merged and styled successfully!" << std::endl;

    Aspose::Cells::Cleanup();
}

Supprimer une Plage Nommée

Aspose.Cells fournit la méthode NameCollection.RemoveAt() pour effacer le nom de la plage. Pour effacer le contenu de la plage, utilisez la méthode Cells.ClearRange(). L’exemple suivant montre comment supprimer une plage nommée avec son contenu.

#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\\");

    // Instantiate a new Workbook
    Workbook workbook;

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

    // Get the first worksheet in the worksheets collection
    Worksheet worksheet = workbook.GetWorksheets().Get(0);

    // Create a range of cells
    Range range1 = worksheet.GetCells().CreateRange(u"E12", u"I12");

    // Name the range
    range1.SetName(u"MyRange");

    // Set the outline border to the range
    range1.SetOutlineBorder(BorderType::TopBorder, CellBorderType::Medium, Color::AliceBlue());
    range1.SetOutlineBorder(BorderType::BottomBorder, CellBorderType::Medium, Color::Red());
    range1.SetOutlineBorder(BorderType::LeftBorder, CellBorderType::Medium, Color::AliceBlue());
    range1.SetOutlineBorder(BorderType::RightBorder, CellBorderType::Medium, Color::Red());

    // Input some data with some formattings into a few cells in the range
    range1.Get(0, 0).PutValue(u"Test");
    range1.Get(0, 4).PutValue(u"123");

    // Create another range of cells
    Range range2 = worksheet.GetCells().CreateRange(u"B3", u"F3");

    // Name the range
    range2.SetName(u"testrange");

    // Copy the first range into second range
    range2.Copy(range1);

    // Remove the previous named range (range1) with its contents
    worksheet.GetCells().ClearRange(11, 4, 11, 8);
    worksheets.GetNames().RemoveAt(0);

    // Save the excel file
    workbook.Save(outDir + u"copyranges.out.xls");

    Aspose::Cells::Cleanup();
}
