获取单元格索引

可能的使用场景

当您只需通过行和列索引操作工作表上的特定数据时,您需要了解该特定单元格的行索引和列索引。 Aspose.Cells for Node.js via C++ 提供此功能,根据行名、列名和单元格名获取对应的行和列索引。 Aspose.Cells for Node.js via C++提供以下属性和方法,帮助你实现目标。

注意:在 Aspose.Cells for Node.js via C++ 中索引从零开始,但在 MS Excel 中行的 ID 是从一开始的。

使用 Aspose.Cells for Node.js via C++ 获取单元格索引

此示例演示如何:

  1. 创建一个工作簿并添加一些数据。
  2. 在第一个工作表中查找特定单元格。
  3. 通过单元格名称获取行索引和列索引。
  4. 通过列名获取列索引。
  5. 通过行名获取行索引。
const AsposeCells = require("aspose.cells.node");
var workbook = new AsposeCells.Workbook(AsposeCells.FileFormatType.Xlsx);
var cells = workbook.getWorksheets().get(0).getCells();
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.putValue(30);
cell = cells.get("C5");
cell.putValue(60);
var curr = cells.find("Blackberry", null);
//var curr = cells.get("A4");
console.log("Current Cell Name: " + curr.getName());
//get row and column index of current cell
var rowCol = AsposeCells.CellsHelper.cellNameToIndex(curr.getName());
var currRow = rowCol[0];
var currCol = rowCol[1];
console.log("Row Index: " + currRow + " Column Index: " + currCol);
//get column name by column index
var columnName = AsposeCells.CellsHelper.columnIndexToName(currCol);
//get row name by row index
var rowName = AsposeCells.CellsHelper.rowIndexToName(currRow);
console.log("Column Name: " + columnName + " Row Name: " + rowName);
//get column index by column name
var columnIndex = AsposeCells.CellsHelper.columnNameToIndex(columnName);
//get row index by row name
var rowIndex = AsposeCells.CellsHelper.rowNameToIndex(rowName);
console.log("Column Index: " + columnIndex + " Row Index: " + rowIndex);
console.log(columnIndex == currCol);
console.log(rowIndex == currRow);
