 *  - Set the Order: you can now add a form field (hidden) labeled "e_gs_order" and set its defualt value to the names of the columns you want to seperated by comma in the order you want, any other colum not in that list will be added after.
 *  - Exclude Columns: you can now add a field (could be hidden) labeled "e_gs_exclude" and set its value to the names of the columns you want to exclude seperated by comma.
