Help - Sort field custom.

[former_member517543]

guiding myself with some threads I tried to sort the table using the custom fields. the problem that does not order them correctly. I have read that the fields filled in in the get do not store the data in the node. and I have propagated using the set but it does not allow the change. so I only have to order with the data shown instead of the node. I need some help to do it.
