Format a Table in a Word Document Using the Syncfusion .NET Word Library

Tables help arrange the Word document content in rows and columns. A row is a horizontal collection of cells and a column is a vertical collection of cells. Each cell can contain multiple paragraphs and additional tables. The Syncfusion^® .NET Word library allows users to create and format tables with just a few lines of code in C# without relying on Microsoft Word or interop dependencies.

Format tables in Word documents using C#

Learn how to format tables in Word documents programmatically using C# with the Syncfusion .NET Word Library. This guide demonstrates applying table formatting properties like borders and alignment to customize table appearance.

Step 1: Create a new project

Start by creating a new C# Console Application project.

Step 2: Install the NuGet package

Add the Syncfusion.DocIO.Net.Core package to your project from NuGet.org.

Step 3: Add required namespaces to format table

Add the following namespaces to your Program.cs file:

c#
using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.Drawing;
using System.IO;

Step 4: Open the Word document and access table

Open an existing Word document and access the first table in the document.

c#
FileStream fileStreamPath = new FileStream(Path.GetFullPath(@"Data/Template.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
 //Create an instance of WordDocument class (Empty Word Document)
 WordDocument document = new WordDocument();
 //Open an existing Word document into DocIO instance
 document.Open(fileStreamPath, FormatType.Docx);
 //Access the instance of the first section in the Word document
 WSection section = document.Sections[0];
 //Access the instance of the first table in the section
 WTable table = section.Tables[0] as WTable;

Step 5: Apply table formatting properties

Apply various formatting properties to customize the table appearance and styling.

c#
// Set the title for the table
  table.Title = "PriceDetails";
  // Set the description of the table
  table.Description = "This table shows the price details of various fruits";
  // Set the left indent of the table
  table.IndentFromLeft = 50;
  // Set the background color of the table
  table.TableFormat.BackColor = Color.FromArgb(192, 192, 192);
  // Set the horizontal alignment of the table
  table.TableFormat.HorizontalAlignment = RowAlignment.Left;
  // Set the left, right, top and bottom padding of all the cells in the table
  table.TableFormat.Paddings.All = 10;
  // Set the auto resize of table to automatically resize all cell width based on its content
  table.TableFormat.IsAutoResized = true;
  // Set the table top, bottom, left and right border line width
  table.TableFormat.Borders.LineWidth = 2f;
  // Set the table horizontal border line width
  table.TableFormat.Borders.Horizontal.LineWidth = 2f;
  // Set the table vertical border line width
  table.TableFormat.Borders.Vertical.LineWidth = 2f;
  // Set the tables top, bottom, left and right border color
  table.TableFormat.Borders.Color = Color.Red;
  // Set the table Horizontal border color
  table.TableFormat.Borders.Horizontal.Color = Color.Red;
  // Set the table vertical border color
  table.TableFormat.Borders.Vertical.Color = Color.Red;
  // Set the table borders border type
  table.TableFormat.Borders.BorderType = BorderStyle.Double;

Step 6: Access and format the first row

Access the first row of the table and apply height formatting properties.

c#
//Access the instance of the first row in the table
WTableRow row = table.Rows[0];
// Set the row height
row.Height = 20;
// Set the row height type
row.HeightType = TableRowHeightType.AtLeast;

Step 7: Save the Word document

Save the formatted Word document to a file stream.

Run

c#
//Create file stream
FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Output.docx"), FileMode.Create, FileAccess.ReadWrite);
//Save the Word document to file stream
document.Save(outputFileStream, FormatType.Docx);
outputFileStream.Close();
document.Close();
fileStreamPath.Close();
