eiceblue profile image E-iceblue Product Family ・4 min read

Tables in electronic documents are usually used for displaying tabular data. However, in some specific types of documents, such as PowerPoint and HTML, tables can also be used for creating modern flat graphics.

This article will show you how to create an ordinary table and a stylish table graphic in a PowerPoint document by using Free Spire.Presentation for Java.

Create a Normal Table

import com.spire.presentation.*;

public class NormalTable {

    public static void main(String[] args) throws Exception {

        //create a Presentation instance
        Presentation presentation = new Presentation();
        presentation.getSlideSize().setType(SlideSizeType.SCREEN_16_X_9);

        //define column widths and row heights
        Double[] widths = new Double[]{100d, 100d, 100d, 150d, 100d,100d};
        Double[] heights = new Double[]{15d, 15d, 15d, 15d, 15d};

        //add a table
        ITable table = presentation.getSlides().get(0).getShapes().appendTable((float)(presentation.getSlideSize().getSize().getWidth() - 650)/2, 40, widths, heights);

        //define data
        String[][] data = new String[][]
                {
                        {"Emp#", "Name", "Job", "HiringD", "Salary", "Dept#"},
                        {"7369", "Andrews", "Engineer", "05/12/2006", "1600.00", "20"},
                        {"7499", "Nero", "Technician", "03/23/2006", "1800.00", "30"},
                        {"7521", "Adams", "Technician", "11/03/2007", "2400.00", "30"},
                        {"7566", "Martin", "Manager", "12/21/2007", "2600.00", "10"},
                };

        for (int i = 0; i < data.length; i++) {
            for (int j = 0; j < data[i].length; j++) {

                //fill the table with data
                table.get(j, i).getTextFrame().setText(data[i][j]);

                //align text in each cell to center
                table.get(j, i).getTextFrame().getParagraphs().get(0).setAlignment(TextAlignmentType.CENTER);
            }
       }

        //apply built-in table style
        table.setStylePreset(TableStylePreset.DARK_STYLE_2_ACCENT_3_ACCENT_4);

        //save the document
        presentation.saveToFile("output/NormalTable.pptx", FileFormat.PPTX_2013);
    }
}

Output:
Format text content
