By default, the report types display every available report field and the table scrolls from left to right if there is too much data to fit horizontally. If you want to remove any of the columns, right-click on the header row in any report type to bring up the column selection contextual menu, as shown in Figure 6.2:

Figure 6.2. Choosing Report Columns

The ARM Profiler displays all of the checked report fields. To hide a report field and its associated column, select it in the contextual menu. To un-hide the column, re-open the contextual menu and select the report field again. Any number of columns can be hidden in this manner so that functions, classes, files and call chains reports display only the information that you find valuable.
