visually corrupted DT

Description of problem:
It is possible to change the order of columns in a Guided DT (In the table definition part of the editor, where you can edit the column definitions, you can grab the line and drag it up and down the list). If you do that while a column is hidden, a ghost column appears in the data part of the editor - see screenshot.

The problem is only visual, the source is okay. Editing a cell, after setting the column back to visible, helps.


Version-Release number of selected component (if applicable):
kie-wb 6.0 CR1


Steps to Reproduce:
1. Create a Decision Table, (add a condition column), add 2 action columns.
2. Add a row and input some data.
3. Set the second action column to be hidden.
4. Move the hidden action column up in the list.
