When you display a list as a hierarchy, you can show or hide subordinate data.
A hierarchy level is created in the first column from every hierarchy column (see Setting Hierarchy Columns). Each entry of a hierarchy level that contains subordinate data is indicated by a small arrow icon . Lower hierarchy levels are slightly indented. Data from the lowest hierarchy level is indicated by a point.
The Airline column contains the names of airlines. The Flight Number column contains the flight numbers for all flights. The remaining columns contain detailed data for the flights for each airline, such as flight date, and price.
