[xwiki-users] Livetable additional elements in table fields

Hi, Is there a way to display additional things inside a Livetable field to interact with the field value shown? For example I have a livetable showing all application documents as follows: Name | Category | User | Password | Modify Date | Actions For every entry in the User and Password columns I want to provide a button to copy the respective field value to the clipboard. How can I modify the livetable to have additional elements alongside the field value? Thanks in advance, Dennis
