Compose Tables with Aspose.Note

Introduction

Tables are fundamental components of documents, enabling structured presentation of information. Aspose.Note for .NET provides robust tools to compose tables effortlessly. In this tutorial, we’ll guide you through the process of creating tables with rich text content using Aspose.Note.

Prerequisites

Before diving into table composition with Aspose.Note for .NET, ensure you have the following prerequisites:

1. Environment Setup: Make sure you have a suitable development environment set up with .NET Framework or .NET Core.
2. Installation: Download and install Aspose.Note for .NET from the website.
3. Basic Knowledge: Familiarize yourself with the basic concepts of C# programming and document manipulation.

Import Namespaces

Before you start composing tables, ensure you import the necessary namespaces:

using System;
using System.Drawing;
using System.IO;
using System.Linq;

Let’s break down the example provided into manageable steps:

Step 1: Set Up the Document Directory

Before composing the table, define the directory where the document will be saved.

string dataDir = "Your Document Directory";

Step 2: Create Header Text

Define the header text with specific styles such as font size and boldness.

var headerText = new RichText() { ParagraphStyle = new ParagraphStyle() { FontSize = 18, IsBold = true }, Alignment = HorizontalAlignment.Center }
					.Append("Super contest for suppliers.");

Step 3: Create Page and Outline

Initialize a page and an outline to structure the content.

var page = new Page();
var outline = page.AppendChildLast(new Outline() { HorizontalOffset = 50 });
outline.AppendChildLast(new OutlineElement()).AppendChildLast(headerText);

Step 4: Add Summary Text

Include a summary text before the table.

var bodyTextHeader = outline.AppendChildLast(new OutlineElement()).AppendChildLast(new RichText() { ParagraphStyle = ParagraphStyle.Default });
bodyTextHeader.Append("This is the final ranking of proposals got from our suppliers.");

Step 5: Create Table

Initialize a table to organize data in rows and columns.

var ranking = outline.AppendChildLast(new OutlineElement()).AppendChildLast(new Table());

Step 6: Add Header Row

Populate the table with a header row containing column titles.

var headerRow = ranking.AppendChildFirst(new TableRow());
foreach (var header in new[] { "Supplier", "Contacts", "Score A", "Score B", "Score C", "Final score", "Attached materials", "Comments" })
{
   ranking.Columns.Add(new TableColumn());
   headerRow.AppendChildLast(new TableCell() { BackgroundColor = backGroundColor })
			 .AppendChildLast(new OutlineElement())
			 .AppendChildLast(new RichText() { ParagraphStyle = headerStyle })
			 .Append(header);
}

Step 7: Add Empty Rows

Insert empty rows to prepare for data insertion.

for (int i = 0; i < 5; i++)
{
   backGroundColor = backGroundColor.IsEmpty ? Color.LightGray : Color.Empty;
   var row = ranking.AppendChildLast(new TableRow());
   for (int j = 0; j < ranking.Columns.Count(); j++)
   {
	   row.AppendChildLast(new TableCell() { BackgroundColor = backGroundColor })
		  .AppendChildLast(new OutlineElement())
		  .AppendChildLast(new RichText() { ParagraphStyle = ParagraphStyle.Default });
   }
}

Step 8: Add Contact Information

Populate the ‘Contacts’ column with template content.

foreach (var row in ranking.Skip(1))
{
   var contactsCell = row.ElementAt(1);
   contactsCell.AppendChildLast(new OutlineElement())
			   .AppendChildLast(new RichText() { ParagraphStyle = ParagraphStyle.Default })
			   .Append("Web: ").Append("link", new TextStyle() { HyperlinkAddress = "www.link.com", IsHyperlink = true });
   contactsCell.AppendChildLast(new OutlineElement())
			   .AppendChildLast(new RichText() { ParagraphStyle = ParagraphStyle.Default })
			   .Append("E-mail: ").Append("mail", new TextStyle() { HyperlinkAddress = "mailto:[e-mail]", IsHyperlink = true });
}

Step 9: Save the Document

Save the composed table document.

var d = new Document();
d.AppendChildLast(page);
d.Save(Path.Combine(dataDir, "ComposeTable_out.one"));

Step 10: Confirmation

Confirm successful document composition.

Console.WriteLine("\nThe document is composed successfully.");
