How to change the column header dynamically in advance table.

To change the column of a header dynamically use the following code in your controller.
import oracle.apps.fnd.framework.webui.beans.table.OAAdvancedTableBean;
import oracle.apps.fnd.framework.webui.beans.table.OAColumnBean;
import oracle.apps.fnd.framework.webui.beans.table.OASortableHeaderBean;

OAAdvancedTableBean tableBean = (OAAdvancedTableBean)webBean.findIndexedChildRecursive(“VendordtlRN”);
OAColumnBean columnBean = (OAColumnBean)tableBean.findIndexedChildRecursive(“SupplierID”);
OASortableHeaderBean colHeaderBean = (OASortableHeaderBean)columnBean.getColumnHeader();
colHeaderBean.setText(“Vendor Name”);
