Tables are a fundamental part of many PDF documents, and styling them can significantly enhance the visual presentation of your data. In this article, we will guide you through the process of styling table elements in PDFs using Java and Aspose.PDF.

Prerequisites

Before we begin, make sure you have the following:

  • Java development environment
  • Aspose.PDF for Java library
  • Basic knowledge of Java programming

Setting Up Aspose.PDF for Java

To get started, download the Aspose.PDF for Java library from the website: Download Aspose.PDF for Java

Once downloaded, include the library in your Java project.

Creating a PDF Document

Let’s start by creating a new PDF document using Aspose.PDF for Java.

// Java code to create a PDF document
Document pdfDocument = new Document();

Adding a Table

Now, let’s add a table to our PDF document. We can specify the number of rows and columns for the table.

// Java code to add a table
Table table = new Table();
table.setColumnWidths("100");
pdfDocument.getPages().get_Item(1).getParagraphs().add(table);

Styling the Table

To style the table, you can customize various aspects such as cell background color, text font, and more.

// Java code to style the table
table.setDefaultCellBorder(new BorderInfo(BorderSide.All, 1F));
table.setDefaultCellPadding(new MarginInfo(5, 5, 5, 5));
table.setDefaultCellTextState(new TextState());

Adding Data to the Table

Let’s add some data to the table. You can populate the cells with your desired content.

// Java code to add data to the table
Row row = table.getRows().add();
row.getCells().add("Name");
row.getCells().add("Age");
row.getCells().add("Country");

// Add more rows and data as needed

Customizing Table Borders

You can further customize the table borders to achieve the desired look.

// Java code to customize table borders
table.setBorder(new BorderInfo(BorderSide.All, 2F));

Formatting Cell Content

Formatting cell content, such as text alignment and font style, can be done easily.

// Java code to format cell content
TextState textState = new TextState();
textState.setFont(FontRepository.findFont("Arial"));
textState.setFontSize(12);
textState.setForegroundColor(Color.getBlack());

cell.setTextState(textState);
cell.setAlignment(HorizontalAlignment.Center);

Adding Headers and Footers

Headers and footers are essential for PDF documents. You can add them to your table as needed.

// Java code to add headers and footers
HeaderFooter header = new HeaderFooter();
table.setTop(header);

Saving the PDF Document

Finally, save the PDF document to your desired location.

// Java code to save the PDF document
pdfDocument.save("styled_table_example.pdf");
