Import Packages

Firstly, make sure you have imported the necessary packages into your Java project:

import com.aspose.slides.ITable;
import com.aspose.slides.Presentation;

Step 1: Load the Presentation

To begin, load the PowerPoint presentation that contains the table you want to modify.

// Specify the path to your PowerPoint document
String dataDir = "Your Document Directory";
Presentation pres = new Presentation(dataDir + "table.pptx");

Step 2: Access the Slide and Table

Navigate to the slide containing the table and access the table object.

// Access the first slide
ISlide slide = pres.getSlides().get_Item(0);
// Initialize a variable to hold the table reference
ITable table = null;
// Iterate through shapes to find the table
for (IShape shape : slide.getShapes()) {
    if (shape instanceof ITable) {
        table = (ITable) shape;
        break;
    }
}

Step 3: Set the First Row as Header

Once the table is identified, set the first row as a header.

// Check if table is found
if (table != null) {
    // Set the first row as header
    table.setFirstRow(true);
}

Step 4: Save and Dispose

Finally, save the modified presentation and dispose of the resources.

// Save the presentation
pres.save(dataDir + "output.pptx", SaveFormat.Pptx);
// Dispose of the Presentation object
pres.dispose();
