Dynamic datatable for columns and rows jsf (JSF2) - jsf

Question

I actually followed below link added columns and row data as dynamic, little confused on how to show on xhtml. any help
http://balusc.blogspot.com/2006/06/using-datatables.html#PopulateDynamicDatatable
List<String> strlist = new ArrayList<String>();
List<List<String>> dynamicListynamicList = new ArrayList<List<String>>();
strlist.add("Name");
strlist.add("SSN");
for(String columnName : columnNamesList){
strlist.add(columnName);
}
List<String> rowData = new ArrayList<String>();
for(String otherList : listData){
try {
rowData.add(otherList.getName());
rowData.add(otherList.getId());
if(otherList.getAmount() != null){
for(BigDecimal amount : otherList.getAmount()){
if(amount != null){
rowData.add(amount.toString());
}else{
rowData.add("");
}
}
}else{
for(String s : strlist){
rowData.add("");
}
}
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
dynamicListynamicList.add(Arrays.asList(rowData.toArray(new String[rowData.size()] )));
}
String[] strarray = new String[strlist.size()];
dynamicHeaders = strlist.toArray(strarray );
populateDynamicDataTable(dynamicListynamicList);
private void populateDynamicDataTable(List<List<String>> dynamicList2){
HtmlDataTable dynamicDataTable = new HtmlDataTable();
for (int i = 0; i < dynamicList2.get(0).size(); i++) {
HtmlColumn column = new HtmlColumn();
dynamicDataTable.getChildren().add(column);
HtmlOutputText header = new HtmlOutputText();
header.setValue(createValueExpression("#{dynamicItemColumn[" + dynamicHeaders[i] + "]}", String.class));
column.setHeader(header);
HtmlOutputText output = new HtmlOutputText();
output.setValueExpression("value",
createValueExpression("#{dynamicItem[" + i + "]}", String.class));
column.getChildren().add(output);
}
dynamicDataTableGroup = new HtmlPanelGroup();
dynamicDataTableGroup.getChildren().add(dynamicDataTable);
setDynamicList(dynamicList2);
every thing works fine as data being added, now i wasnt sure and my apologies, how to iterate in jsf page(xhtml), to show relvant columna nd rowdata..
