تنسيق وتعديل النطاقات المعرفة باستخدام Node.js عبر C++

تنسيق النطاقات

ضبط لون الخلفية وسمات الخط لنطاق مسمى

لتطبيق التنسيق، قم بتعريف كائن Style لتحديد إعدادات النمط وتطبيقه على كائن Range.

المثال التالي يوضح كيفية ضبط لون التعبئة الصلبة (لون الظل) مع إعدادات الخط إلى نطاق.

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"));

إضافة حدود إلى نطاق مسمى

من الممكن إضافة حدود إلى نطاق من الخلايا بدلاً من خلية واحدة فقط. يوفر كائن Range طريقة setOutlineBorder(BorderType, CellBorderType, CellsColor) التي تأخذ المعلمات التالية لإضافة حد إلى نطاق الخلايا:

• نوع الحد، نوع الحد، مختار من تعداد BorderType.
• نمط الخط، نمط الخط، مختار من تعداد CellBorderType.
• اللون، لون الخط، مختار من تعداد الألوان.

يظهر المثال التالي كيفية تعيين حد للنطاق.

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"));

المثال التالي يوضح كيفية ضبط حدود حول كل خلية في النطاق.

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"));

إعادة تسمية نطاق مسمى

تسمح Aspose.Cells لك بإعادة تسمية النطاق المعرف لأغراضك. يمكنك الحصول على النطاق المعرف وإعادة تسميته باستخدام سمة Name.getText(). يعرض المثال التالي كيفية إعادة تسمية نطاق معرف.

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"));

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"));

تقاطع النطاقات

توفر Aspose.Cells طريقة Range.intersect(Range) لتقاطع نطاقين. تعيد هذه الطريقة كائن Range. للتحقق مما إذا كان نطاق معين يتداخل مع نطاق آخر، استخدم طريقة Range.intersect(Range) التي تعيد قيمة Boolean. يوضح المثال التالي كيفية تقاطعات النطاقات.

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"));

// 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"));

إزالة نطاق مسمى

توفر Aspose.Cells الطريقة NameCollection.removeAt(number) لمسح اسم النطاق. لمسح محتويات النطاق، استخدم طريقة Cells.clearRange(CellArea). يوضح المثال التالي كيفية إزالة نطاق معرف مع محتوياته.

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

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

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"));
