This patch allows adjusting the width of the element surrounding the LiveGrid if it permits this via the special attribute 'autoresize="1"'. This is especially useful when the surrounding element is a table column (<td>) and there's another element next to the LiveGrid. Without this patch, the grid won't be able to use the entire space it should.
If this patch cannot be included in the next version of Rico, maybe something similar could be implemented, i.e. resizing of the surrounding elements of the LiveGrid.
