Working with Table Parameters in Templates

Introduction

In this tutorial, we’ll explore how to use GroupDocs.Parser for .NET to work with table parameters in templates. This guide will break down the process into step-by-step instructions to help you effectively parse and extract data from tables within documents.

Prerequisites

Before we begin, make sure you have the following prerequisites in place:

  • GroupDocs.Parser for .NET Library: You can download the library from here.
  • Development Environment: Ensure you have a suitable development environment set up for .NET development.
  • Sample Document: Prepare a sample document (e.g., PDF, DOCX) that contains tables from which you want to extract data.

Import Namespaces

First, you’ll need to import the necessary namespaces for working with GroupDocs.Parser in your .NET application:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using GroupDocs.Parser.Data;
using GroupDocs.Parser.Templates;

Step 1: Create a Table Template

To work with table parameters, start by defining a table template with specific parameters:

// Define table parameters (position and size)
TemplateTableParameters tableParams = new TemplateTableParameters(new Rectangle(new Point(35, 320), new Size(530, 55)), null);
// Create a TemplateTable object with parameters and a title
TemplateTable table = new TemplateTable(tableParams, "Details", null);

Step 2: Create a Template

Now, assemble your template with the defined table:

// Create a Template object and include the table in it
Template template = new Template(new TemplateItem[] { table });

Step 3: Parse Document Using Template

Utilize the Parser class to parse your document based on the created template:

// Provide the path to your sample document
string filePath = "Your Sample File Path";
// Create an instance of the Parser class with the document path
using (Parser parser = new Parser(filePath))
{
    // Parse the document using the template
    DocumentData data = parser.ParseByTemplate(template);
    // Iterate through extracted data
    for (int i = 0; i < data.Count; i++)
    {
        Console.Write(data[i].Name + ": ");
        
        // Check if the extracted field is a table
        PageTableArea area = data[i].PageArea as PageTableArea;
        if (area == null)
        {
            continue;
        }
        // Iterate through table rows
        for (int row = 0; row < area.RowCount; row++)
        {
            // Iterate through table columns
            for (int column = 0; column < area.ColumnCount; column++)
            {
                // Get the cell value
                PageTextArea cellValue = area[row, column].PageArea as PageTextArea;
                // Print the cell value (with tab separation)
                Console.Write(cellValue == null ? "" : cellValue.Text + "\t");
            }
            
            // Move to the next line for the next row
            Console.WriteLine();
        }
    }
}

Conclusion

In this tutorial, we’ve covered how to effectively work with table parameters in templates using GroupDocs.Parser for .NET. By following these steps, you can efficiently extract structured data from tables within your documents.
