Table In Header Footer Section

In this tutorial, we will guide you step by step on how to add a table in the header or footer section of a PDF document using Aspose.PDF for .NET. The provided C# source code shows you how to create an empty PDF document, add a page, configure the header section, create a table, add rows and cells to the table, and finally save the PDF document.

Step 1: Setting up the environment

Before you begin, make sure you have the following:

An installed .NET development environment.
The Aspose.PDF library for .NET downloaded and referenced in your project.

Step 2: Creating the PDF Document and Page

The first step is to create an instance of the Document class and add a page to the document. Here’s how:

// The path to the documents directory.
string dataDir = "YOUR DOCUMENTS DIRECTORY";

// Instantiate a Document object
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document();

// Create a page in the PDF document
Aspose.Pdf.Page page = pdfDocument.Pages.Add();

Be sure to replace “YOUR DOCUMENTS DIRECTORY” with the actual path to the directory where you want to save the PDF document.

Step 3: Configuring the header section

Now we will configure the header section of the PDF document by creating an instance of the HeaderFooter class. Here’s how:

// Create a header section for the PDF file
Aspose.Pdf.HeaderFooter header = new Aspose.Pdf.HeaderFooter();

// Define the header section for the page
page. Header = header;

// Set the top margin of the header section
header. Margin. Top = 20;

Step 4: Creating the table

Now we are going to create a table using the Table class and add it to the heading section’s paragraph collection. Here’s how:

// Instantiate a Table object
Aspose.Pdf.Table tab1 = new Aspose.Pdf.Table();

// Add the table to the paragraphs collection of the header section
header.Paragraphs.Add(tab1);

// Define the widths of the columns of the table
tab1.ColumnWidths = "60,300";

The code above creates a table with two columns of specified widths.

Step 5: Add rows and cells to the table

Now we will add rows and cells to the table using the Row class and the Cell class. Here’s how:

// Create a row in the table and add cells
Aspose.Pdf.Row row1 = tab1.Rows.Add();
row1.Cells.Add("Table in header section");
row1.BackgroundColor = Color.Gray;

// Merge the first cell of the first row
tab1.Rows[0].Cells[0].ColSpan = 2;
tab1.Rows[0].Cells[0].DefaultCellTextState.ForegroundColor = Color.Cyan;
tab1.Rows[0].Cells[0].DefaultCellTextState.Font = FontRepository.FindFont("Helvetica");

// Create another row in the table and add a cell with an image
Aspose.Pdf.Row row2 = tab1.Rows.Add();
row2.BackgroundColor = Color.White;
Aspose.Pdf.Cell cell2 = row2.Cells.Add();
Aspose.Pdf.Image img = new Aspose.Pdf.Image();
img.File = dataDir + "aspose-logo.jpg";
img. FixWidth = 60;
cell2.Paragraphs.Add(img);
row2.Cells.Add("The logo is beautiful!");
row2.Cells[1].DefaultCellTextState.Font = FontRepository.FindFont("Helvetica");
row2.Cells[1].VerticalAlignment = Aspose.Pdf.VerticalAlignment.Center;
row2.Cells[1].Alignment = Aspose.Pdf.HorizontalAlignment.Center;

Step 6: Saving the PDF Document

Once the table has been added to the header section, we can save the PDF document. Here’s how:

// Save the PDF file
pdfDocument.Save(dataDir + "TableInHeaderFooterSection_out.pdf");

Be sure to replace “YOUR DOCUMENTS DIRECTORY” with the actual path to the directory where you want to save the PDF document.

Sample source code for Table In Header Footer Section using Aspose.PDF for .NET


// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";

// Instantiate Document instance by calling empty constructor
Aspose.Pdf.Document pdfDocument = new Aspose.Pdf.Document();

// Create a page in the pdf document
Aspose.Pdf.Page page = pdfDocument.Pages.Add();

// Create a Header Section of the PDF file
Aspose.Pdf.HeaderFooter header = new Aspose.Pdf.HeaderFooter();

// Set the Odd Header for the PDF file
page.Header = header;

// Set the top margin for the header section
header.Margin.Top = 20;

// Instantiate a table object
Aspose.Pdf.Table tab1 = new Aspose.Pdf.Table();

// Add the table in paragraphs collection of the desired section
header.Paragraphs.Add(tab1);

// Set default cell border using BorderInfo object
tab1.DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 0.1F);

// Set with column widths of the table
tab1.ColumnWidths = "60 300";
Aspose.Pdf.Image img = new Aspose.Pdf.Image();
img.File = dataDir + "aspose-logo.jpg";

// Create rows in the table and then cells in the rows
Aspose.Pdf.Row row1 = tab1.Rows.Add();
row1.Cells.Add("Table in Header Section");
row1.BackgroundColor = Color.Gray;

// Set the row span value for first row as 2
tab1.Rows[0].Cells[0].ColSpan = 2;
tab1.Rows[0].Cells[0].DefaultCellTextState.ForegroundColor = Color.Cyan;
tab1.Rows[0].Cells[0].DefaultCellTextState.Font = FontRepository.FindFont("Helvetica");

// Create rows in the table and then cells in the rows
Aspose.Pdf.Row row2 = tab1.Rows.Add();

// Set the background color for Row2
row2.BackgroundColor = Color.White;

// Add the cell which holds the image
Aspose.Pdf.Cell cell2 = row2.Cells.Add();

// Set the image width to 60
img.FixWidth = 60;

// Add the image to the table cell
cell2.Paragraphs.Add(img);
row2.Cells.Add("Logo is looking fine !");
row2.Cells[1].DefaultCellTextState.Font = FontRepository.FindFont("Helvetica");

// Set the vertical allignment of the text as center alligned
row2.Cells[1].VerticalAlignment = Aspose.Pdf.VerticalAlignment.Center;
row2.Cells[1].Alignment = Aspose.Pdf.HorizontalAlignment.Center;

// Save the Pdf file
pdfDocument.Save(dataDir + "TableInHeaderFooterSection_out.pdf");
