Problems with copy value TableColumn invisible

Question

To hide (make invisible) TableColumns normally do:

TableColumn.setMinWidth(0);
TableColumn.setMaxWidth(0);

or remove from the model with removeColumn method (column);

But at run time we have the need to leave invisible or visible the column and ends up being more practical to use setMinWidth (0) and setMaxWidth (0).

This creates a problem because if the user selects a table row and press Ctrl+C and paste it into a text file, it can copy the value of the hidden column!!!

We could to solve the problem using TransferHandler to not perform CopyAction of JComponent. How TableColumn is not a JComponent would not give to solve this way.

Another alternative would be to define: (JTable to disallow selection lines)

JTable.setRowSelectionAllowed(false)

Well this last solution would not be feasible for me because I need to keep the permit selection of rows in the table. Does anyone have another solution to restrict copying of values from all the columns?

For better help sooner, post an [SSCCE](http://sscce.org/). – Andrew Thompson Jan 07 '14 at 10:48 — Andrew Thompson, Jan 07 '14 at 10:48

To hide (make invisible) TableColumns normally do:

TableColumn.setMinWidth(0);
TableColumn.setMaxWidth(0);

this isn't good way, playing with zero size, this column isn't hiddenonly has un_natural size, still is accesible for all mouse & key events
you have to removeColumn() from JTables view

Thanks for the reply You know what it would prevent the copying action even for the visible columns? – user3168661 Jan 07 '14 at 11:11
