Both column sizing and sorting are maintained on a per user basis, and only for the report where the column changes are made.
Report columns can be resized. Resize a report column by clicking on the edge of the report title box and moving it either left or right. When a report column is resized, the new size is saved and used each time the report is viewed.
Most monitor report columns can be sorted. You can sort by left-clicking a column heading. The report column then automatically sorts itself either ascending or descending. The sort direction is indicated with an upward, or downward pointing arrow.
As in column sizing, column sorting settings are saved and are used each time the report is viewed.
