Aspose.PDF Table Generator for .NET

Aspose.PDF Table Generator for .NET is a streamlined plugin designed exclusively for creating, manipulating, and rendering tables in PDF documents. Built on the Aspose.PDF core engine, it provides fine-grained control over rows, columns, formatting, and layout. Whether generating simple reports or complex nested tables with dynamic content, it ensures high performance and seamless integration into .NET applications.

Getting Started

Installation and Setup

  1. Install Aspose.PDF via NuGet or download assemblies directly.

    dotnet add package Aspose.PDF

  2. Configure metered licensing early in your application (see Metered Licensing ).

Features and Functionalities

Table Creation and Layout

  • Define rows, columns, widths (absolute or relative), and alignment.
  • Control borders, padding, and table-wide styles.
  • Fit tables to full-page width or dynamic container sizes.

Data Binding and Dynamic Content

  • Populate tables cell-by-cell or bind to enumerable data sources.
  • Use templating to replace placeholders with runtime values.
  • Generate invoices, reports, and catalogs directly from collections.

Styling and Formatting

  • Apply fonts, colors, backgrounds, and borders to cells, rows, or columns.
  • Conditional formatting based on values (e.g., highlight negatives).
  • Reusable style templates for consistency and reduced file size.

Cell Merging and Splitting

  • Merge cells across rows or columns to create spans.
  • Split merged regions back into individual cells as needed.

Complex Table Structures

  • Support for nested tables inside cells.
  • Mix text, images, and sub-tables in layouts.
  • Insert tables into existing PDF pages without affecting other content.

Performance Optimization

  • Incremental streaming for large data sets.
  • Lazy resource loading avoids serializing unused styles.
  • Efficient for thousands of rows with minimal memory use.

Interoperability

  • Append tables to existing PDFs.
  • Extract and modify previously generated tables.
  • Resize, reposition, or restyle without re-rendering the document.

Code Example: Creating Tables in PDF 

// Define input and output PDF paths
var inputPath = Path.Combine(@"C:\Samples\", "sample.pdf");
var outputPath = Path.Combine(@"C:\Samples\", "output.pdf");

// Create Table Generator instance
var generator = new TableGenerator();

// Configure table options
var options = new TableOptions();
options.Columns.Add(new Column { Width = 100 });
options.Columns.Add(new Column { Width = 200 });
options.Rows.Add(new Row
{
    Cells =
    {
        new Cell { Text = "Product" },
        new Cell { Text = "Price" }
    }
});

// Add input and output
options.AddInput(new FileDataSource(inputPath));
options.AddOutput(new FileDataSource(outputPath));

// Process table generation
generator.Process(options);
Console.WriteLine("Table added successfully.");

Tips and Best Practices

  • Reuse style templates for fonts, borders, and backgrounds.
  • Process rows in batches for large datasets to reduce memory use.
  • Avoid excessive nesting—flatten layouts when possible.
  • Pre-validate row/column definitions to avoid exceptions.
  • Use page-break hints to keep header rows intact across pages.
  • Always configure licensing early to avoid watermarked output.
