Values from columns of datatable...

Question

Hi guys,
i'm working with my jsf application to create a datatable.
It works well,but now i've added a commandlink button to dynamically adding a new column(i use this datatable for input data,each row is an experiment).
It works fine,column is correctly added.
At the end of each row of my datatable i've a submit button to send values of the row into db.
My question is:
My datatable has 5 fixed fields and other dinamic fields that user can add with button. My 5 fixed values have to go into a table(and it works) and i want that dynamic values(that use has added) go into another table,each one as a different row.
Example
usa italy french england japan rome tokyo
i want usa italy french englan japan go into a table(as a row) and rome tokio goes into another table
rome
tokio(different rows).
How can i do it?
My problem is i'm not able to binding the dynamic input fields to bean....can you help me?
Here is my class
public class BiosamplesTable {
     private List biosamples= new ArrayList();
     private HtmlDataTable biosampleDataTable;
private int autokey2;
     private Biosample biosampleItem;
     private int nrows;
     private DataModel mColumns;
     private int load=0;
     private String columnLabel;
     public HtmlDataTable getBiosampleDataTable()  {
          return biosampleDataTable;
     public void setBiosampleDataTable(HtmlDataTable biosampleDataTable) {
          this.biosampleDataTable = biosampleDataTable;
     public Biosample getBiosampleItem() {
          return biosampleItem;
     public void setBiosampleItem(Biosample biosampleItem) {
          this.biosampleItem = biosampleItem;
     public List getBiosamples() throws Exception {
          loadBiosamples();
          // Reload after every request.
          return biosamples;
     public void setBiosamples(List biosamples) {
          this.biosamples = biosamples;
     public void loadBiosamples() throws Exception {
          if (load==0){
          for (int i = 0; i < nrows; i++) {
               Biosample biosample = new Biosample();
               biosamples.add(biosample);
               setBiosamples(biosamples);
               load=1;
          else
               setBiosamples(biosamples);
     public int getNrows() {
          return nrows;
     public void setNrows(int nrows) {
          this.nrows = nrows;
     public DataModel getColumnDataModel()
         if (mColumns == null)
           String[] result = new String[]{};//sono le colonne di partenza,in questo caso 1!!!
           mColumns = new ListDataModel(new ArrayList(Arrays.asList(result)));
         return mColumns;
     public void addColumn(ActionEvent e)
         if(columnLabel!=null);//metter l'if
           List columns = (List) getColumnDataModel().getWrappedData();
           columns.add(columnLabel);
     public String getColumnLabel(){
          return columnLabel;
     public void setColumnLabel(String columnLabel){
          this.columnLabel=columnLabel;
}and this is my jsp page

u can't achieve this with DataTable u need tu use JSTL ...exactly the
C-Tag
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
