Bookmark Table Columns In Word Document

In this article, we will explore the C# source code above to understand how to use the Bookmark Table Columns function in the Aspose.Words for .NET library. This feature allows you to bookmark a specific column of a table in a Word document and access the content of that column.

Prerequisites

• Basic knowledge of the C# language.
• .NET development environment with Aspose.Words library installed.

Step 1: Creating the table

Before creating a bookmark on a table column, we must first create the table using a DocumentBuilder object. In our example, we create a table with two rows and two columns:

builder. StartTable();

builder. InsertCell();

builder. StartBookmark("MyBookmark");

builder.Write("This is cell 1 of row 1");

builder. InsertCell();
builder.Write("This is cell 2 of row 1");

builder. EndRow();

builder. InsertCell();
builder.Writeln("This is cell 1 of row 2");

builder. InsertCell();
builder.Writeln("This is cell 2 of row 2");

builder. EndRow();
builder. EndTable();

Step 2: Creating the column bookmark

We use the StartBookmark method to create a bookmark on a specific column of the table. In our example, we use the name “MyBookmark” for the bookmark:

builder. StartBookmark("MyBookmark");

Step 3: Access the column content

We go through all the bookmarks in the document and display their names. If a bookmark is a column, we access the contents of that column using the column index and the GetText method:

foreach (Bookmark

  bookmark in doc.Range.Bookmarks)
{
Console.WriteLine("Bookmark: {0}{1}", bookmark.Name, bookmark.IsColumn?" (Column)": "");

if (bookmark.IsColumn)
{
if (bookmark.BookmarkStart.GetAncestor(NodeType.Row) is Row row && bookmark.FirstColumn < row.Cells.Count)
Console.WriteLine(row.Cells[bookmark.FirstColumn].GetText().TrimEnd(ControlChar.CellChar));
}
}

Example source code for Bookmark Table Columns using Aspose.Words for .NET

Here is the full sample source code to demonstrate creating a bookmark on a table column using Aspose.Words for .NET:

	
	Document doc = new Document();
	DocumentBuilder builder = new DocumentBuilder(doc);

	builder.StartTable();
	
	builder.InsertCell();

	builder.StartBookmark("MyBookmark");

	builder.Write("This is row 1 cell 1");

	builder.InsertCell();
	builder.Write("This is row 1 cell 2");

	builder.EndRow();

	builder.InsertCell();
	builder.Writeln("This is row 2 cell 1");

	builder.InsertCell();
	builder.Writeln("This is row 2 cell 2");

	builder.EndRow();
	builder.EndTable();
	
	builder.EndBookmark("MyBookmark");
	

	
	foreach (Bookmark bookmark in doc.Range.Bookmarks)
	{
		Console.WriteLine("Bookmark: {0}{1}", bookmark.Name, bookmark.IsColumn ? " (Column)" : "");

		if (bookmark.IsColumn)
		{
			if (bookmark.BookmarkStart.GetAncestor(NodeType.Row) is Row row && bookmark.FirstColumn < row.Cells.Count)
				Console.WriteLine(row.Cells[bookmark.FirstColumn].GetText().TrimEnd(ControlChar.CellChar));
		}
	}
