Creating dynamic dataTables **Very Urgent**

Question

Hi all,
I m very new to JSF Technology. I m in need of creating dynamic dataTables. I need to populate the values from DB. At times, the number of columns varies. So, how can i create such kind of table? At least i need to know how can i create dataTable values using the Backing bean and mapping it to the JSF page, so that the browser will render that dataTable?
Please help me.. :)

The following code (taken from the BalusC article) do the task:
            // Create <h:column>.
            HtmlColumn column = new HtmlColumn();
            dynamicDataTable.getChildren().add(column);
            // Create <h:outputText value="dynamicHeaders"> for <f:facet name="header"> of column.
HtmlOutputText header = new HtmlOutputText();
header.setValue(dynamicHeaders[i]);
column.setHeader(header);
// Create <h:outputText value="#{dynamicItem[" + i + "]}"> for the body of column.
HtmlOutputText output = new HtmlOutputText();
output.setValueExpression("value",
createValueExpression("#{dynamicItem[" + i + "]}", String.class));
column.getChildren().add(output);
