@Simpel Thanks! I will work on it:
https://portal.igfae.usc.es/xwiki/bin/view/Table/
I’ve been not able yet to create data sources pointing to remote databases (not the one where XWiki data are stored) to feed Live Data Macro. I’m using the objects you proposed and Make Tables Sortable Macro in my way to fully understand Live Data Macro.
Any idea or comment is extremely welcome! Thanks!
