Delete Excel table (ListObject) rows without affecting other columns using XlsIO
Syncfusion® Excel (XlsIO) library is a .NET Excel library used to create, read, and edit Excel documents. It also, converts Excel documents to PDF files. Using this library, you can perform row-column manipulations in Excel tables (ListObjects) using C# and VB.NET.
While working with ListObjects in Excel, you might need to delete one or more rows in a table but not the columns next to the table. This article explains how to delete rows of ListObjects in Excel file without affecting other columns in the same rows with an example.
Steps to delete ListObject rows in Excel, programmatically:
Step 1: Create a new C# console application project.
Create a new C# console application
Step 2: Install the Syncfusion.XlsIO.WinForms NuGet package as a reference to your .NET Framework applications from the NuGet.org.
Install NuGet package
Step 3: Include the following namespaces in the Program.cs file.
C#
using Syncfusion.XlsIO; using Syncfusion.Drawing; using System.IO; using System.Reflection;
VB.NET
Imports Syncfusion.XlsIO Imports Syncfusion.Drawing Imports System.IO Imports System.Reflection
Step 4: Add the following code snippet to delete a row in ListObject using C# and VB.NET.
C#
// Create an instance of ExcelEngine using (ExcelEngine excelEngine = new ExcelEngine()) { // Initialize application IApplication application = excelEngine.Excel; // Open existing workbook with sample table Assembly assembly = typeof(Program).GetTypeInfo().Assembly; Stream fileStream = assembly.GetManifestResourceStream("XlsIOSample.table.xlsx"); IWorkbook workbook = application.Workbooks.Open(fileStream, ExcelOpenType.Automatic); // Access worksheet and a listobject in it IWorksheet worksheet = workbook.Worksheets[0]; IListObject table = worksheet.ListObjects[0]; table.Name = "SalesTable"; // Delete a listobject row, with parameters as listobject and row number to be deleted Program className = new Program(); className.DeleteListRow(table, 4); // Saves the modified workbook workbook.SaveAs("Output.xlsx"); }
VB.NET
'Create an instance of ExcelEngine Using excelEngine As ExcelEngine = New ExcelEngine() 'Initialize application Dim application As IApplication = excelEngine.Excel 'Open existing workbook with data entered Dim assembly As Assembly = GetType(Module1).GetTypeInfo.Assembly Dim fileStream As Stream = assembly.GetManifestResourceStream("XlsIOSample_VB.table.xlsx") Dim workbook As IWorkbook = application.Workbooks.Open(fileStream, ExcelOpenType.Automatic) 'Access worksheet and a listobject in it Dim worksheet As IWorksheet = workbook.Worksheets(0) Dim table As IListObject = worksheet.ListObjects(0) table.Name = "SalesTable" 'Delete a listobject row, with parameters as listobject and row number to be deleted DeleteListRow(table, 4) 'Saves the modified workbook workbook.SaveAs("Output.xlsx") End Using
The following DeleteListRow(IListObject, int) method can be used to delete a table row without affecting the columns outside the table range, by specifying the (worksheet) row number.
C#
private void DeleteListRow(IListObject table, int rowNumber) { IRange tableRange = table.Location; IWorksheet worksheet = table.Worksheet; int firstTableColumn = tableRange.Column; int lastTableColumn = tableRange.LastColumn; int firstTableRow = tableRange.Row; int lastTableRow = tableRange.LastRow; table.Worksheet[rowNumber, firstTableColumn, rowNumber, lastTableColumn].Clear(ExcelClearOptions.ClearContent); if (rowNumber < tableRange.LastRow) { for (int i = rowNumber + 1; i <= lastTableRow; i++) { worksheet.Range[i, firstTableColumn, i, lastTableColumn].MoveTo(worksheet.Range[i - 1, firstTableColumn, i - 1, lastTableColumn]); } } table.Location = table.Location[firstTableRow, firstTableColumn, lastTableRow - 1, lastTableColumn]; }
VB.NET
Private Sub DeleteListRow(ByVal table As IListObject, ByVal rowNumber As Integer) Dim tableRange As IRange = table.Location Dim worksheet As IWorksheet = table.Worksheet Dim firstTableColumn As Integer = tableRange.Column Dim lastTableColumn As Integer = tableRange.LastColumn Dim firstTableRow As Integer = tableRange.Row Dim lastTableRow As Integer = tableRange.LastRow table.Worksheet(rowNumber, firstTableColumn, rowNumber, lastTableColumn).Clear(ExcelClearOptions.ClearContent) If (rowNumber < tableRange.LastRow) Then For i As Integer = rowNumber + 1 To lastTableRow worksheet.Range(i, firstTableColumn, i, lastTableColumn).MoveTo(worksheet.Range(i - 1, firstTableColumn, i - 1, lastTableColumn)) Next table.Location = table.Location(firstTableRow, firstTableColumn, lastTableRow - 1, lastTableColumn) End If End Sub
A complete working example to delete ListObject rows in Excel along with input file containing a sample table can be downloaded from DeleteListObjectRows.zip.
By executing the program, you will get the output Excel file as shown below.
