Create PDF Tables

This guide shows you to create a PDF Table with UniPDF. With this knowledge, You can include tables in your PDFs and perform other PDF functionalities.

Before you begin #

You should get your API key from your UniCloud account.

If this is your first time using UniPDF SDK, follow this guide to set up a local development environment.

Project setup #

Clone the project repository #

In your terminal, clone the examples repository. It contains the Go code we will be using for this guide.

git clone https://github.com/unidoc/unipdf-examples.git

Change into the repository directory and navigate to the report folder

cd unipdf-examples/report

Configure environment variables #

Replace the UNIDOC_LICENSE_API_KEY with your API credentials from your UniCloud account.

Linux/Mac #

export UNIDOC_LICENSE_API_KEY=PUT_YOUR_API_KEY_HERE

Windows #

set UNIDOC_LICENSE_API_KEY=PUT_YOUR_API_KEY_HERE

How it works #

In this example, you will see the different ways you can use UniPDF packages to create and customize tables.

Lines 9-18 import the UniPDF packages and other required dependencies.

Lines 20-27 authenticate your request with your UNIDOC_LICENSE_API_KEY with the init function.

In the main function lines 29-72, we create a new instance of the PDF creator using the .New() method. In this guide, we will be saving the output to unidoc-tables.pdf.

Lines 74-94 generates the front page for the PDF. We will also draw a footer for each of the pages using the .drawFooter from lines 96-108 and generate a table of contents with the .TOCmethod from lines 110-129.

From here, you can choose to experiment with creating basic or advanced tables in your PDF.

For a basic PDF with tables, Lines 131-150 creates a new chapter with the NewChapter function and creates three subchapters in the new chapter showing how tables work in UniPDF.

In the first subchapter, we create a table and align its content horizontally similar to working with text in an editor.

In the second subchapter, we create a table and align its content vertically similar to working with text in an editor.

In the third subchapter, we create a table and illustrate wrapping and aligning text to fit a cell.

Lines 152-428 creates a new chapter with three subschapters showing how to style the content in your table.

From Lines 430-711, we have the advanced table in detail. We created a new chapter with three subchapters, each subchapter with a table showing how to span a table content across columns, set rows as headers and create subtables in a table.

Run the code #

Run this command to create the PDF. This will also get all the required dependencies to run the program automatically.

go run pdf_tables.go

Sample output #

Open the created PDF in any PDF viewer, and you should get a 7-paged PDF like this.
