In list screens, you can set which columns are displayed in which order. To the right of each list screen is the 
button. This opens the light-box Setting up columns:
Visible - Not visible
The fields that are on the left are shown as columns in the list screen. The fields that are on the right are not displayed. The fields can be dragged and dropped from left to right and vice versa.
Order
The order of the visible columns (left to right) is determined by the order of the fields (top to bottom).
