Problem with Dynamic table having row map.

Question

Hi,
I need to create a table dynamically based on following inputs:
a.)Name and number of columns will be decided dynamically at run-time.
b.) Each row will contain a map of column values ,which will be dynamically generated by some other class.
In the same way multiple tables need to be created dynamically.
I tried created table for the same as following:
RichTable tb=new RichTable();
tb.setId("trs");
tb.setValue(UICredRowList.getMapListforRows());
for(Iterator itr=header.iterator();itr.hasNext();)
String headerKey = (String) itr.next();
RichColumn myCol = new RichColumn();
ExpressionFactory efact = FacesContext.getCurrentInstance(). getApplication().getExpressionFactory();
ValueExpression valExpr1 = efact.createValueExpression( elContext1,"#{row["+headerKey+"]}",Object.class);
resolveExpression("#{row["+headerKey+"]}") ;
myCol.setId("tc1");
myCol.setSortable(false);
myCol.setWidth("250");
myCol.setHeaderText(headerKey);
RichOutputText rot1 = new RichOutputText();
rot1.setValueExpression("value", valExpr1);
myCol.getChildren().add(rot1);
tb.getChildren().add(myCol);
Here when I checked the column value from Expression I am getting value as null.
                    Can someone help me how can I handle this type of table.Example will be highly appreciated.
Thanks in Advance
Sunil

Which JDeveloper version do you use, if you use 12c or 11R2 you should find this option when you drag and drop the table to auto generate columns dynamically.
