[xwiki-users] launch scheduled job and flamengo skin with table

Hello Today I have two questions :-) Are they a way to launch some scheduled jobs of xwiki  by cron? With flamengo skin on xwiki 6.0RC1 this table: |= en-tête |= en-tête |= en-tête | cellule | cellule | cellule | cellule | cellule | cellule  is displayed like this: http://snag.gy/Dlvpu.jpg Is it normal?
