Formatear y modificar rangos con nombre con Node.js mediante C++

Formato de rangos

Establecer el color de fondo y los atributos de fuente a un rango con nombre

Para aplicar formato, define un objeto Style para especificar la configuración de estilo y aplícalo al objeto Range.

El siguiente ejemplo muestra cómo establecer el color de relleno sólido (color de sombreado) con la configuración de fuente a un rango.

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"));

Agregar bordes a un rango con nombre

Es posible agregar bordes a un rango de celdas en lugar de solo una celda. El objeto Range proporciona un método setOutlineBorder(BorderType, CellBorderType, CellsColor) que toma los siguientes parámetros para agregar un borde al rango de celdas:

  • Tipo de borde, el tipo de borde, seleccionado del enumerado BorderType.
  • Estilo de línea, el estilo de línea, seleccionado del enumerado CellBorderType.
  • Color, el color de la línea, seleccionado del enumerado Color.

El siguiente ejemplo muestra cómo establecer un borde de contorno en un rango.

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"));

El siguiente ejemplo muestra cómo establecer bordes alrededor de cada celda en el rango.

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"));

Renombrar un rango con nombre

Aspose.Cells permite cambiar el nombre de un rango con nombre según sea necesario. Puedes obtener el rango con nombre y cambiarle el nombre usando el atributo Name.getText(). El siguiente ejemplo muestra cómo renombrar un rango con nombre.

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"));

Unión de rangos

Aspose.Cells proporciona el método Range.unionRang(Range) para unir rangos; el método devuelve un objeto Array. El siguiente ejemplo muestra cómo unir rangos.

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"));

Intersección de rangos

Aspose.Cells proporciona el método Range.intersect(Range) para intersectar dos rangos. El método devuelve un objeto Range. Para verificar si un rango interseca con otro, usa el método Range.intersect(Range) que devuelve un valor booleano. El siguiente ejemplo muestra cómo intersectar los rangos.

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"));

Combinar celdas en el rango con nombre

Aspose.Cells proporciona el método Range.merge() para fusionar las celdas en el rango. El siguiente ejemplo muestra cómo fusionar las celdas individuales de un rango con nombre.

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"));

Eliminar un Rango Nombrado

Aspose.Cells proporciona el método NameCollection.removeAt(number) para borrar el nombre del rango. Para borrar el contenido del rango, usa el método Cells.clearRange(CellArea). El siguiente ejemplo muestra cómo eliminar un rango con nombre con su contenido.

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"));
