Presentation with Tables

This guide shows how to create a presentation with a table using UniOffice.

Before you begin #

You should get your API key from your UniCloud account.

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

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/unioffice-examples

To get the example navigate to the path presentation/tables folder in the unioffice-examples directory.

cd unioffice-examples/presentation/tables/

How it works #

The import section in lines 4-12, imports the necessary packages. The init function in lines 14-21, sets the license key using license.SetMeteredKey(os.Getenv(`UNIDOC_LICENSE_API_KEY`)).

The main function of the example code is defined in lines 21-60. In lines 22-24, a new presentation object is created, and a new slide is instantiated using:

ppt := presentation.New()
defer ppt.Close()
slide := ppt.AddSlide()

The defer statement here makes sure that the presentation object is closed, and the temporary resources, if any, are cleared at the end. In line 26, a new table is created using slide.AddTable(). Then the columns are set using the for loop in lines 27-30. We can tell the number of columns intended to be created from the for loop range.

In lines 31-45, the outer loop creates a table row and the inner loop populates the columns of each row with a text. In lines 47-58, the styles of the table are set. Finally, the presentation is written to file in line 59 using ppt.SaveToFile("out.pptx").

Run the code #

Run this command to generate the presentation file with a table.
