import javax.servlet.annotation.WebServlet;

import com.vaadin.annotations.Theme;
import com.vaadin.annotations.VaadinServletConfiguration;

import com.vaadin.server.VaadinRequest;

@VaadinServletConfiguration(productionMode = false, ui = Testproject1UI.class)

@Override

    Table table = new Table("Patient Data");
    
    table.addContainerProperty("Name", String.class, null);
    table.addContainerProperty("Location", String.class, null);
    table.addContainerProperty("SSN", String.class, null);
    table.addContainerProperty("Age",Integer.class , null);
    // Add a few other rows using shorthand addItem()
    Item item = table.addItem("TIM");
    item.getItemProperty("Name").setValue("Tim");
    item.getItemProperty("Location").setValue("room 453");
    item.getItemProperty("SSN").setValue("2343-654");
    item.getItemProperty("Age").setValue(new Integer(21));

    // Show exactly the currently contained rows (items)
    table.setPageLength(table.size());
    table.setVisible(true);
}

Hi,

you’re not adding the Table to the UI or any layout in your code. Try adding e.g. setContent(table); into your init method. Could be that you need some sizing or a layout too, depending on your needs.
