使用C++获取单元格索引

Excel的默认视图是A1样式引用，其中每列定义为A、B、C等等，单元格命名为A1、B2、C3……等。 你可能想知道该单元格属于哪一行和哪一列。

可能的使用场景

当你只需要通过行和列索引操作特定数据时，你需要知道该单元格的行和列索引。 Aspose.Cells提供此功能，以通过行、列和单元格的名称获取行和列索引。 Aspose.Cells提供以下属性和方法帮助你实现目标：

• CellsHelper::CellNameToIndex
• CellsHelper::ColumnIndexToName
• CellsHelper::ColumnNameToIndex
• CellsHelper::RowIndexToName
• CellsHelper::RowNameToIndex

注意：在Aspose.Cells for 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 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。

    // Obtaining the reference of the newly added worksheet

    Cells cells = ws.GetCells();

    // Setting the value to the cells
    Cell cell = cells.Get(u"A1");
    cell.PutValue(u"Fruit");
