插入、删除行和列

介绍

无论是从头开始创建新工作表还是处理现有工作表，我们都可能需要添加额外的行或列以容纳更多数据。反之，我们可能还需要删除工作表中指定位置的行或列。为满足这些要求，Aspose.Cells 提供了一组非常简单的类和方法，如下所述。

管理行和列

Aspose.Cells提供了一个类，工作簿，代表一个 Microsoft Excel 文件。这工作簿类包含一个工作表允许访问 Excel 文件中每个工作表的集合。工作表由工作表班级。这工作表类提供了一个细胞代表工作表中所有单元格的集合。

这细胞collection 提供了多种方法来管理工作表中的行和列。下面讨论其中一些。

添加行或列时，工作表中的内容向下或向右移动，如果删除行或列，则内容向上或向左移动。

插入一行

通过调用插入行的方法细胞收藏。这插入行方法采用将插入新行的行的索引。

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

//Path of input excel file
StringPtr sampleInsertingDeletingRowsAndColumns = dirPath->StringAppend(new String("sampleInsertingDeletingRowsAndColumns.xlsx"));

//Path of output excel file
StringPtr outputInsertingDeletingRowsAndColumns = outPath->StringAppend(new String("outputInsertingDeletingRowsAndColumns.xlsx"));

//Read input excel file
intrusive_ptr<IWorkbook> workbook = Factory::CreateIWorkbook(sampleInsertingDeletingRowsAndColumns);

//Accessing the first worksheet in the Excel file
intrusive_ptr<IWorksheet> worksheet = workbook->GetIWorksheets()->GetObjectByIndex(0);

//Inserting a row into the worksheet at 3rd position
worksheet->GetICells()->InsertRow(2);

//Save the Excel file.
workbook->Save(outputInsertingDeletingRowsAndColumns);

插入多行

要将多行插入到工作表中，请调用插入行的方法细胞收藏。这插入行方法有两个参数：

• 行索引，将插入新行的行的索引。
• Number of rows，需要插入的总行数。

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

//Path of input excel file
StringPtr sampleInsertingDeletingRowsAndColumns = dirPath->StringAppend(new String("sampleInsertingDeletingRowsAndColumns.xlsx"));

//Path of output excel file
StringPtr outputInsertingDeletingRowsAndColumns = outPath->StringAppend(new String("outputInsertingDeletingRowsAndColumns.xlsx"));

//Read input excel file
intrusive_ptr<IWorkbook> workbook = Factory::CreateIWorkbook(sampleInsertingDeletingRowsAndColumns);

//Accessing the first worksheet in the Excel file
intrusive_ptr<IWorksheet> worksheet = workbook->GetIWorksheets()->GetObjectByIndex(0);

//Inserting 10 rows into the worksheet starting from 3rd row
worksheet->GetICells()->InsertRows(2, 10);

//Save the Excel file.
workbook->Save(outputInsertingDeletingRowsAndColumns);

删除多行

要从工作表中删除多行，请调用删除行的方法细胞收藏。这删除行方法有两个参数：

• 行索引，将从中删除行的行的索引。
• 行数，需要删除的总行数。

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

//Path of input excel file
StringPtr sampleInsertingDeletingRowsAndColumns = dirPath->StringAppend(new String("sampleInsertingDeletingRowsAndColumns.xlsx"));

//Path of output excel file
StringPtr outputInsertingDeletingRowsAndColumns = outPath->StringAppend(new String("outputInsertingDeletingRowsAndColumns.xlsx"));

//Read input excel file
intrusive_ptr<IWorkbook> workbook = Factory::CreateIWorkbook(sampleInsertingDeletingRowsAndColumns);

//Accessing the first worksheet in the Excel file
intrusive_ptr<IWorksheet> worksheet = workbook->GetIWorksheets()->GetObjectByIndex(0);

//Deleting 10 rows from the worksheet starting from 3rd row
worksheet->GetICells()->DeleteRows(2, 10);

//Save the Excel file.
workbook->Save(outputInsertingDeletingRowsAndColumns);

插入一列

开发人员还可以通过调用插入列的方法细胞收藏。插入列方法采用将插入新列的列的索引。

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

//Path of input excel file
StringPtr sampleInsertingDeletingRowsAndColumns = dirPath->StringAppend(new String("sampleInsertingDeletingRowsAndColumns.xlsx"));

//Path of output excel file
StringPtr outputInsertingDeletingRowsAndColumns = outPath->StringAppend(new String("outputInsertingDeletingRowsAndColumns.xlsx"));

//Read input excel file
intrusive_ptr<IWorkbook> workbook = Factory::CreateIWorkbook(sampleInsertingDeletingRowsAndColumns);

//Accessing the first worksheet in the Excel file
intrusive_ptr<IWorksheet> worksheet = workbook->GetIWorksheets()->GetObjectByIndex(0);

//Inserting a column into the worksheet at 2nd position
worksheet->GetICells()->InsertColumn(1);

//Save the Excel file.
workbook->Save(outputInsertingDeletingRowsAndColumns);

删除列

要从工作表的任何位置删除列，请调用删除列的方法细胞收藏。这删除列方法采用要删除的列的索引。

//For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

//Path of input excel file
StringPtr sampleDeleteColumn = dirPath->StringAppend(new String("sampleInsertingDeletingRowsAndColumns.xlsx"));

//Path of output excel file
StringPtr outputDeleteColumn = outPath->StringAppend(new String("outputInsertingDeletingRowsAndColumns.xlsx"));

//Read input excel file
intrusive_ptr<IWorkbook> workbook = Factory::CreateIWorkbook(sampleDeleteColumn);

//Accessing the first worksheet in the Excel file
intrusive_ptr<IWorksheet> worksheet = workbook->GetIWorksheets()->GetObjectByIndex(0);

//Deleting a column from the worksheet at 2nd position
worksheet->GetICells()->DeleteColumn(4);

//Save the Excel file.
workbook->Save(outputDeleteColumn);
