JSF datatable - any difference with JSF 1.1 and JSF 1.2

Question

Hi All,
In my project there are lot of Datatables, which retrieve data from the database and display it to the user. For each datatable, the columns are not fixed. I want to create some kind of component that can be reusable.
It is basically a JSF portlet. Now i have to use RAD 6. RAD 6 supports only JSF1.1. I have to migrate this to RAD7 in the near future. Are there any differences between the Datatable in JSF 1.1 and JSF 1.2?
I had this approach in mind.
a) Create the datatable programmatically and put the contents to panelgrid. This way the jsp code will be minimized. Is it a good option.? Are the APIs same in both the versions?
b) Is it possible to create a custom datatable which can take some key as input. Then based on the key the datatable can be populated with as many columns as desired.
Please let me know if there are any other good options.

Hi guys,
my code goes like this..
for (int j = 0; j < size; j++) {
               UIColumn column = new UIColumn();
               dataTable.getChildren().add(column);
               HtmlOutputText header = new HtmlOutputText();
               header.setValue(periodHeader[j]);
               column.setHeader(header);
               HtmlOutputText output = new HtmlOutputText();
               output.setValue(new Double(periodLiability[j]));
               ValueBinding vb1 = FacesContext.getCurrentInstance()
                         .getApplication().createValueBinding(
                                   ("#{liability.periodLiability["+j+"]}"));
               output.setValueBinding("value", vb1);
               column.getChildren().add(output);
this code gives me the number of headers i need. But, it doesnt render the columns. I have an array of Double (periodLiability) which stores few values of Double type. I want to show thesee values inthe dataTable Column.
Please help me..
