Customizing the Elements Table Tab
Note: If some elements are grouped, the total group loss value is compared with
the addition of the thresholds defined for the individual elements in the
group. If the total group loss value is greater than the addition of the
thresholds defined for the individual elements in group, the element will
show a fail status. You can individually select grouped elements as any
other standalone element. When elements are grouped at the beginning of
the link, icon A is displayed on one of the sub-elements. When elements are
grouped at the end of the link, icon B is displayed on one of the
sub-elements.
