[SOLVED] Change the cell width in new widget area

Thanks Flynn for the great update on the new widget function, now I can create my page menu bar and
feed subscribe icons in the same line.

This is what I defined for the new widget in header,
The first cell I use PixoPoint Multi-level Navigation Plugin to create stylish menus, and the second cell to place feed subscribe icons. But the width parameters of two cells are not pass to the final code, they equal to half of the maximum width 1050.

You can check the result at my blog, http://thdp.org/
Could you tell me what's wrong with this?

Thanks,
