How do I turn off text wrap in the items column and widen the width of it for the 'Group Pick Rank'

In reference to the photo, how do I turn off text wrap in the items column and widen the width of it. I don't want the white gap between the items column and group column.
Here are the codes I have already:
.Skin .PGR .DragAndDrop .NoColumns td.groupsContainerTd div h2,.Skin .PGR .DragAndDrop .NoColumns td.groupsContainerTd div ul{width:600px}
.Skin .PGR .DragAndDrop .NoColumns td.groupsContainerTd div>div{width:600px}

.Skin .PGR .DragAndDrop td.groupsContainerTd div > div { border: 1px solid; border-collapse: collapse; min-height: 20px; height: 80px; }

.Skin .SkinInner {width: 95%}
