Formattare e modificare intervalli denominati con Node.js tramite C++

Formattare intervalli

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

Per applicare la formattazione, definisci un oggetto Style per specificare le impostazioni di stile e applicalo all’oggetto Range.

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

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiate a new Workbook.
const workbook = new AsposeCells.Workbook();

// Get the first worksheet in the book.
const WS = workbook.getWorksheets().get(0);

// Create a range of cells.
const range = WS.getCells().createRange(1, 1, 1, 18);

// Name the range.
range.setName("MyRange");

// Declare a style object.
let stl;

// Create/add the style object.
stl = workbook.createStyle();

// Specify some Font settings.
stl.getFont().setName("Arial");
stl.getFont().setIsBold(true);

// Set the font text color
stl.getFont().setColor(AsposeCells.Color.Red);

// To Set the fill color of the range, you may use ForegroundColor with
// Solid Pattern setting.
stl.setForegroundColor(AsposeCells.Color.Yellow);
stl.setPattern(AsposeCells.BackgroundType.Solid);

// Create a StyleFlag object.
let flg = new AsposeCells.StyleFlag();
// Make the corresponding attributes ON.
flg.setFont(true);
flg.setCellShading(true);

// Apply the style to the range.
range.applyStyle(stl, flg);

// Save the excel file.
workbook.save(path.join(dataDir, "rangestyles.out.xls"));

Aggiunta di bordi a un intervallo nominato

È possibile aggiungere bordi a un intervallo di celle invece di una singola cella. L’oggetto Range offre un metodo setOutlineBorder(BorderType, CellBorderType, CellsColor) 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 linea, lo stile della linea, selezionato dall’enumerazione CellBorderType.
  • Colore, il colore della linea, selezionato dall’enumerazione dei Colori.

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

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiating a Workbook object
const workbook = new AsposeCells.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
const worksheet = workbook.getWorksheets().get(0);

// Accessing the "A1" cell from the worksheet
const cell = worksheet.getCells().get("A1");

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

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

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

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

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

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

// Saving the Excel file
workbook.save(path.join(dataDir, "book1.out.xls"));

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

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "sample.xlsx");

// Loads the workbook which contains hidden external links
const workbook = new AsposeCells.Workbook(filePath);

// Access the cells in the first worksheet.
const cells = workbook.getWorksheets().get(0).getCells();

// Create a range of cells.
const range = cells.createRange("A6", "P216");

// Declare style.
let stl;

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

// Specify the font settings.
stl.getFont().setName("Arial");
stl.getFont().setIsBold(true);
stl.getFont().setColor(AsposeCells.Color.Blue);

// Set the borders
stl.getBorders().get(AsposeCells.BorderType.TopBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.TopBorder).setColor(AsposeCells.Color.Blue);
stl.getBorders().get(AsposeCells.BorderType.LeftBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.LeftBorder).setColor(AsposeCells.Color.Blue);
stl.getBorders().get(AsposeCells.BorderType.BottomBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.BottomBorder).setColor(AsposeCells.Color.Blue);
stl.getBorders().get(AsposeCells.BorderType.RightBorder).setLineStyle(AsposeCells.CellBorderType.Thin);
stl.getBorders().get(AsposeCells.BorderType.RightBorder).setColor(AsposeCells.Color.Blue);

// Create StyleFlag object.
const flg = new AsposeCells.StyleFlag();
// 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(path.join(dataDir, "output.xls"));

Rinomina un intervallo nominato

Aspose.Cells consente di rinominare un intervallo denominato secondo le proprie esigenze. Puoi ottenere l’intervallo denominato e rinominarlo utilizzando l’attributo Name.getText(). Il seguente esempio mostra come rinominare un intervallo denominato.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Open an existing Excel file that has a (global) named range "TestRange" in it
const workbook = new AsposeCells.Workbook(path.join(dataDir, "book1_testrange.xls"));

// Get the first worksheet
const sheet = workbook.getWorksheets().get(0);

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

// Get the named range "MyRange"
const name = workbook.getWorksheets().getNames().get("TestRange");

// Rename it
name.setText("NewRange");

// Save the Excel file
workbook.save(path.join(dataDir, "RenamingRange.out.xlsx"));

Unione di intervalli

Aspose.Cells fornisce il metodo Range.unionRang(Range) per unire intervalli; il metodo restituisce un oggetto [Array]. Il seguente esempio mostra come unire intervalli.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "book1.xls");
// Instantiate a workbook object.
// Open an existing excel file.
const workbook = new AsposeCells.Workbook(filePath);

// Get the named ranges.
const ranges = workbook.getWorksheets().getNamedRanges();

// Create a style object.
const style = workbook.createStyle();

// Set the shading color with solid pattern type.
style.setForegroundColor(AsposeCells.Color.Yellow);
style.setPattern(AsposeCells.BackgroundType.Solid);

// Create a styleflag object.
const flag = new AsposeCells.StyleFlag();

// Apply the cellshading.
flag.setCellShading(true);

// Creates an array list.
let al = [];

// Get the array list collection apply the union operation.
al = ranges[0].unionRanges([ranges[1]]);

// Define a range object.
let rng;
let frow, fcol, erow, ecol;

for (let i = 0; i < al.length; i++)
{
// Get a range.
rng = al[i];
frow = rng.getFirstRow();
fcol = rng.getFirstColumn();
erow = rng.getRowCount();
ecol = rng.getColumnCount();

// Apply the style to the range.
rng.applyStyle(style, flag);
}

// Save the excel file.
workbook.save(path.join(dataDir, "rngUnion.out.xls"));

Intersezione di intervalli

Aspose.Cells fornisce il metodo Range.intersect(Range) per l’intersezione di due intervalli. Il metodo restituisce un oggetto Range. Per verificare se un intervallo interseca un altro, usa il metodo Range.intersect(Range) che restituisce un valore Booleano. Il seguente esempio mostra come intersectare gli intervalli.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");
const filePath = path.join(dataDir, "book1.xls");

// Instantiate a workbook object.
// Open an existing excel file.
const workbook = new AsposeCells.Workbook(filePath);

// Get the named ranges.
const ranges = workbook.getWorksheets().getNamedRanges();

// Check whether the first range intersect the second range.
const isIntersect = ranges[0].isIntersect(ranges[1]);

// Create a style object.
const style = workbook.createStyle();

// Set the shading color with solid pattern type.
style.setForegroundColor(AsposeCells.Color.Yellow);
style.setPattern(AsposeCells.BackgroundType.Solid);

// Create a styleflag object.
const flag = new AsposeCells.StyleFlag();

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

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

// Name the range.
intersection.setName("Intersection");

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

// Save the excel file.
workbook.save(path.join(dataDir, "rngIntersection.out.xls"));

Unisci celle nell’intervallo nominato

Aspose.Cells fornisce il metodo Range.merge() per unire le celle nell’intervallo. Il seguente esempio mostra come unire le singole celle di un intervallo denominato.

const path = require("path");
const AsposeCells = require("aspose.cells.node");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiate a new Workbook.
const wb1 = new AsposeCells.Workbook();

// Get the first worksheet in the workbook.
const worksheet1 = wb1.getWorksheets().get(0);

// Create a range.
const mrange = worksheet1.getCells().createRange("A18", "J18");

// Name the range.
mrange.setName("Details");

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

// Get the range.
const range1 = wb1.getWorksheets().getRangeByName("Details");      

// Define a style object.
const style = wb1.createStyle();

// Set the alignment.
style.setHorizontalAlignment(AsposeCells.TextAlignmentType.Center);

// Create a StyleFlag object.
const flag = new AsposeCells.StyleFlag();
// 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("Aspose");

// Save the excel file.
wb1.save(path.join(dataDir, "mergingrange.out.xls"));

Rimuovere un intervallo nominato

Aspose.Cells fornisce il metodo NameCollection.removeAt(number) per cancellare il nome dell’intervallo. Per cancellare i contenuti dell’intervallo, usa il metodo Cells.clearRange(CellArea). Il seguente esempio mostra come rimuovere un intervallo denominato con i suoi contenuti.

const AsposeCells = require("aspose.cells.node");
const path = require("path");

// The path to the documents directory.
const dataDir = path.join(__dirname, "data");

// Instantiate a new Workbook.
const workbook = new AsposeCells.Workbook();

// Get all the worksheets in the book.
const worksheets = workbook.getWorksheets();

// Get the first worksheet in the worksheets collection.
const worksheet = worksheets.get(0);

// Create a range of cells.
const range1 = worksheet.getCells().createRange("E12", "I12");

// Name the range.
range1.setName("MyRange");

// Set the outline border to the range.
range1.setOutlineBorder(AsposeCells.BorderType.TopBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));
range1.setOutlineBorder(AsposeCells.BorderType.BottomBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));
range1.setOutlineBorder(AsposeCells.BorderType.LeftBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));
range1.setOutlineBorder(AsposeCells.BorderType.RightBorder, AsposeCells.CellBorderType.Medium, new AsposeCells.Color(0, 0, 128));

// Input some data with some formattings into
// A few cells in the range.
range1.get(0, 0).putValue("Test");            
range1.get(0, 4).putValue("123");

// Create another range of cells.
const range2 = worksheet.getCells().createRange("B3", "F3");

// Name the range.
range2.setName("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(path.join(dataDir, "copyranges.out.xls"));
