set Column id and cell class

Migrateduser

<p>Is there a way to set a columns id and or a cells class in birt?  I have already have my report class inporting a css file to use for its and it has all the generic things like: .report, .table-group-header-1, .table-header etc. Now I would like to add my own classes and id's.  Am I able to do something like: object.addClass(), object.addID()?</p>
