On some tables, the ranking of rows affects how Carbon Black App Control processes rules. For example, on the Custom Rules page, rule number 1 is processed before rule number 2, etc. These tables show rank numbers for each row, and also can be sorted in rank order.
On tables where rank matters, there are arrows in each row (except for special cases) that allow you to move rules so that their rank is higher or lower. In addition, you can drag and drop a row to change its rank in most of these tables, and you can also specify a move location by holding down the left mouse button on the rank number of a rule.
