This might not be the proper place to ask this and it is a very stupid(newbie) question

I have this table, i sort some columns and now i want to know exactly the name of the column that was sorted and in what state it is: sorted ASC , or DESC.
This method: "getSortingColumns()" returns the columns i sort but it;s like this: com.jidesoft.grid.ISortableTableModel$SortItem@1b66aff.
I thought that this object has a property like "getName()" or something, but it doesn't. I might be going in the wrong way here , don't know. If you have an idea please guide me on the right direction.
Thank you
