Jasper Reports: overlapping crosstabs when displayed horizontally

is there a way to have 2 crosstabs inserted next to each others (horizontally) in the title band of the parent report. the problem i am facing is that the second crosstab starts based on it's actual position which makes it overlaps with the first crosstab. I would like to have the second crosstab starts after the first one finishes. it seems that there is no direct way to do this from the studio (the float option works vertically and doesn't work horizontally), does anyone have an idea how this can be done even through the API.

note that i am using Jasper 6.7.0
