To simplify the display of complex tables of data, you can group rows of similar data and sort the grouped bands as well as the data under them. Grouping helps you block distracting data and focus only on the information you need. It also permits you to collapse and expand hierarchical arrangements of your data rather than navigate large flat lists.
You can sort the EPS page, Assignments page, and the Activities page by any columns in your view and specify the order in which column sorts are applied. For example, you might sort by Primary Resource, then Start date, then by Planned duration, and finally by Activity ID. This would mean that if more than one activity has the same Primary Resource, Start Date, and Planned Duration, they will be in the same place in the list and sorted in order of Activity ID.
When you sort your view by multiple columns, the column headings will show numbers representing the sort order as well as an arrow showing whether the sort is ascending or descending. Hierarchies can also be sorted while maintaining the structure of the hierarchy.
