series width can't be controlled by cross tab layout worksheet

Hello
When define series width (in Business Moduler) to  narrow size, When view this series via worksheet as none cross tab format, Series width is ok (series width represented according to the BM definition.)
However, when you change the WS format to cross tab layout, the series width is un controlled.
Q: Is there any option (or trick) to force the series width to remained (as defined in B. moduler?) even in crosstab layout ?

Thanks
