How can I create dynamic datatable in backing bean in jsf (visual jsf)?

----------------> TableGeneric.jsp:
... <h:dataTable binding="#{webs$TableGeneric.dataTable1}" headerClass="list-header" id="dataTable1"  rowClasses="list-row-even,list-row-odd" value="#{webs$TableGeneric.dataTable1Model}">
 </h:dataTable>...
----------------> TableGeneric.java: ...
private HtmlDataTable dataTable1 = new HtmlDataTable(); 
....
public void prerender(){...
   List<HeaderFieldDefinition> header;
   Map<Integer, Map<String, RowField> > rows;
 
   UIColumn column;
   List<UIComponent> childrenList = dataTable1.getChildren();
   childrenList.clear();
   HtmlOutputText headerPrint;
   try{
        /*in tableData there are data and I have everything but I don't actually know write rows in data */
          header = tableData.getHeader();
          rows = tableData.getRows();
 
//in this for loop, I get what I need for name of column, style, etc and via getChildren() and add() //method I map that to a table; but I don't know do that with row 
          for(HeaderFieldDefinition hfd : header){
                column  = new UIColumn();
                headerPrint = new HtmlOutputText();
                headerPrint.setValue(hfd.getName());
                headerPrint.setStyleClass(hfd.getStyleClass());
                column.setHeader(headerPrint);
                childrenList.add(column);
              }
 
//I do something like this for rows, but it's not quite ok:
      int i = childrenList.size();
      
//this is not good: in tempList remember all data like Html...I think that is my problem; I need //something else, I think?!
      List<HtmlOutputText> tempList = new ArrayList<HtmlOutputText>();
      HtmlOutputText row;
 
      Iterator it = rows.entrySet().iterator();
      int p =0;
      while (it.hasNext()) {
             Map<String, RowField> innerMap;
             innerMap = (Map<String, RowField>) ((Map.Entry)it.next()).getValue();
             Iterator iter = innerMap.entrySet().iterator();
             RowField rowField;
             while (iter.hasNext()) {
                    Map.Entry pairs = (Map.Entry)iter.next();
                    rowField = (RowField) pairs.getValue();
                    row = new HtmlOutputText();
                    row.setValue(rowField.getValue());
                    tempList.add(row);
              }
              for(int j = 0; j < i; j++){
                        (childrenList.get(j)).getChildren().add(tempList.get(j));
               }
               p++;
       }
//here I have tempList fill with data and I know there is p rows and i columns...and what now
//System.out.println("--------------> p = "+p + "; i = "+i + "; tempList.size()" + tempList.size());
...}
