Formatera och modifiera namngivna områden med Node.js via C++

** Formatområden**

Ställa in bakgrundsfärg och teckensnittsegenskaper för ett namngivet område

För att tillämpa formatering, definiera ett Style-objekt för att specificera stilinställningarna och tillämpa det på Range-objektet.

Följande exempel visar hur du ställer in en fyllfärg (skuggningsfärg) med teckensnittsinställningar till ett område.

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"));

Lägga till ramar för ett namngivet område

Det är möjligt att lägga till gränser till ett cellområde istället för en enskild cell. Range-objektet tillhandahåller en setOutlineBorder(BorderType, CellBorderType, CellsColor)-metod som tar följande parametrar för att lägga till en gräns till cellområdet:

  • Gränstyp, typen av gräns, vald från BorderType-upplagan.
  • Linjestil, linjens stil, vald från CellBorderType-upplagan.
  • Färg, linjefärgen, vald från Color-upplagan.

Följande exempel visar hur du ställer in en konturram till ett område.

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"));

Följande exempel visar hur man ställer in ramar runt varje cell i området.

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"));

Byt namn på ett namngivet område

Aspose.Cells tillåter dig att byta namn på ett namngivet område efter behov. Du kan hämta det namngivna området och döpa om det med hjälp av Name.getText()-attributet. Följande exempel visar hur man döper om ett namngivet område.

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"));

Förbund av områden

Aspose.Cells tillhandahåller Range.unionRang(Range)-metoden för att ta unionen av områden; metoden returnerar ett [Array]-objekt. Följande exempel visar hur man tar unionen av områden.

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"));

Skärning av områden

Aspose.Cells tillhandahåller Range.intersect(Range)-metoden för att skära mellan två områden. Metoden returnerar ett Range-objekt. För att kontrollera om ett område skär ett annat, använd Range.intersect(Range)-metoden som returnerar ett boolean-värde. Följande exempel visar hur man skär mellan områdena.

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"));

Sammanfoga celler i det namngivna området

Aspose.Cells tillhandahåller Range.merge()-metoden för att slå samman cellerna i området. Följande exempel visar hur man slår samman de individuella cellerna i ett namngivet område.

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"));

Ta bort ett namngivet område

Aspose.Cells tillhandahåller NameCollection.removeAt(number)-metoden för att radera namnet på området. För att rensa innehållet i området, använd Cells.clearRange(CellArea)-metoden. Följande exempel visar hur man tar bort ett namngivet område med dess innehåll.

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"));
