Formatta e modifica intervalli nominati con C++

Formattare intervalli

Impostazione del colore di sfondo e degli attributi del carattere su un intervallo nominato

Per applicare la formattazione, definire un oggetto Style per specificare le impostazioni dello stile e applicarlo all’oggetto Range.

Nell’esempio seguente viene mostrato come impostare il colore di riempimento solido (colore ombreggiatura) con impostazioni del carattere a un intervallo.

#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();
}

Aggiunta di bordi a un intervallo nominato

È possibile aggiungere i bordi a un intervallo di celle invece che a una singola cella. L’oggetto Range fornisce un metodo SetOutlineBorder che accetta i seguenti parametri per aggiungere un bordo all’intervallo di celle:

• Tipo di bordo, il tipo di bordo, selezionato dall’enumerazione BorderType.
• Stile della linea, lo stile della linea, selezionato dall’enumerazione CellBorderType.
• Colore, il colore della linea, selezionato dall’enumerazione Colore.

L’esempio seguente mostra come impostare un bordo di contorno a un intervallo.

#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();
}

Il seguente esempio mostra come impostare i bordi intorno ad ogni cella nell’intervallo.

#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();
}

Rinomina un intervallo nominato

Aspose.Cells ti consente di rinominare un intervallo con nome secondo le tue esigenze. Puoi ottenere l’intervallo con nome e rinominarlo usando l’attributo Name.GetText(). Nell’esempio seguente viene mostrato come rinominare un intervallo con nome.

#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();
}

Unione di intervalli

Aspose.Cells fornisce il metodo Range.UnionRang per unire intervalli, il metodo restituisce un oggetto std::vector. Il seguente esempio mostra come unire gli intervalli.

#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();
}

Intersezione di intervalli

Aspose.Cells fornisce il metodo Range.Intersect per intersecare due intervalli. Il metodo restituisce un oggetto Range. Per verificare se un intervallo interseca un altro intervallo, utilizzare il metodo Range.Intersect che restituisce un valore booleano. L’esempio seguente mostra come intersecare gli intervalli.

#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();
}

Unisci celle nell’intervallo nominato

Aspose.Cells fornisce il metodo Range.Merge() per unergere le celle nell’intervallo. Nell’esempio seguente viene mostrato come unire le celle individuali di un intervallo nominato.

#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();
}

Rimuovere un intervallo nominato

Aspose.Cells fornisce il metodo NameCollection.RemoveAt() per cancellare il nome dell’intervallo. Per cancellare il contenuto dell’intervallo, utilizzare il metodo Cells.ClearRange(). Nell’esempio seguente viene mostrato come rimuovere un intervallo nominato con il suo contenuto.

#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();
