assign space for each column in group

[cap]

while giving the size of each column in the group(have 4 columns) i have used the %, but i don't get it exactly as i like
It says i can use span width..i amtrying to set lke 20px;20px;20px;30Px;
but seems to do not work..space change in strange way
how do i use the span width?and would it be more accurate than percentage?
