title: Primefaces Datatable: need to export additional columns to excel that are not displayed on datatable
body: <p>I have a situation here. I am using prime faces 2.2 where i am showing a data-table on a screen after pulling data from database and displaying the same on data-table. i have 80 columns to retrieve from database but only showing few of them on data-table due to screen size constraints. But while exporting the data-table to excel, i need to export all the 80 columns. Please advise how can we do this the easiest way..Thanks.</p>
