Question

I’ve been trying to fill a JTable for about three days. All I need to do is fill a vector of vectors with “Artikel” objects, fill a header vector and bind these two vectors to a JTable.

I could manage this with using a custom AbstractTableModel but I couldn’t create a addColumn() method. So, I gave up this way. Now I just use standard DefaultTableModel but now I can’t get my JTable right filled. I get all my objects in the first column instead of separated to the all columns:

My Artikel class:

public class Artikel {

private String EnitiativeRef;
private String Brand;
private String pnb;
.
.
.
public Artikel(){        
}

public String getEnitiativeRef() {
    return EnitiativeRef;
}

public void setEnitiativeRef(String EnitiativeRef) {
    this.EnitiativeRef = EnitiativeRef;
}
.
.
.
}

My button code:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

    ICsvBeanReader inFile = null;
    String[] header = {};
    Vector<Vector<Artikel>> data = null;

    try {
        inFile = new CsvBeanReader(new FileReader("C:\\609661920071022111.csv"), CsvPreference.STANDARD_PREFERENCE);

        header = inFile.getHeader(true);

        data = new Vector<Vector<Artikel>>();

        Artikel artikel;
        while ((artikel = inFile.read(Artikel.class, header, cellProcessor)) != null) {
            Vector<Artikel> tmpVector = new Vector<Artikel>();
            tmpVector.addElement(artikel);
            data.addElement(tmpVector);
        }

    } catch (Exception ex) {
        System.out.println("FOUT: " + ex.toString());
    } finally {
        try {
            inFile.close();
        } catch (IOException ex) {
            Logger.getLogger(main.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
    tblAll.setModel(new DefaultTableModel(data, new Vector(Arrays.asList(header))));
    tblAll.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
}

Can you tell me what am I doing wrong or guide me to the right way of doing this? I will really appreciate your grateful help.

Answer 1

Each element in the vector of vectors represents a row and each element of the those element vectors represent a column.

You are adding one-element vectors to the main vector, and the element is an object of the class for which you haven’t implemented the toString method.

You are probably going the wrong way.
