Editable table widget - Disabling Delete Record for certain rows only?

  
 I already looked at this link: 

 http://www.outsystems.com/forums/discussion/13337/editable-tables-what-if-you-dont-need-all-the-features/

But it only covers the general list. I want only to disable the delete record to a certain row. How can this be achieved?
Hi,
This may still need tweaks, but you can try following these instructions.
