获取单元格范围

可能的使用场景

当只需要操作工作表的部分数据时，需了解整个工作表的数据范围。Aspose.Cells for Node.js via C++ 提供此功能，包含以下属性和方法，帮助你实现目标。

• Cells.getMaxDisplayRange
• Cells.getMaxRow
• Cells.getMaxDataRow
• Cells.getMaxColumn
• Cells.getMaxDataColumn

使用Aspose.Cells for Node.js via C++获取单元格范围

此示例演示如何：

1. 创建一个工作簿。
2. 在第一个工作表中的单元格中添加数据。
3. 获取单元格 Range。

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

var workbook = new AsposeCells.Workbook(AsposeCells.FileFormatType.Xlsx);
var cells = workbook.getWorksheets().get(0).getCells();

//Setting the value to the cells
var cell = cells.get("A1");
cell.putValue("Fruit");
cell = cells.get("B1");
cell.putValue("Count");
cell = cells.get("C1");
cell.putValue("Price");

cell = cells.get("A2");
cell.putValue("Apple");
cell = cells.get("A3");
cell.putValue("Mango");
cell = cells.get("A4");
cell.putValue("Blackberry");
cell = cells.get("A5");
cell.putValue("Cherry");

cell = cells.get("B2");
cell.putValue(5);
cell = cells.get("B3");
cell.putValue(3);
cell = cells.get("B4");
cell.putValue(6);
cell = cells.get("B5");
cell.putValue(4);

cell = cells.get("C2");
cell.putValue(5);
cell = cells.get("C3");
cell.putValue(20);
cell = cells.get("C4");
cell.putValue(30);
cell = cells.get("C5");
cell.putValue(60);

cell = cells.get("E10");
var temp = workbook.createStyle();
temp.getFont().setColor(new AsposeCells.Color(255, 0, 0));
cell.setStyle(temp);


// Get max display range of worksheet
var range = cells.getMaxDisplayRange();

//get maximum row index of cell which contains data or style.
console.log(cells.getMaxRow());

//get maximum row index of cell which contains data.
console.log(cells.getMaxDataRow());

//get maximum column index of cell which contains data or style.
console.log(cells.getMaxColumn());

//get maximum column index of cell which contains data.
console.log(cells.getMaxDataColumn());
