Sorting the Right Table by Sample Index
a) Click on the Sample index column header. The table is sorted in ascending order and an upward pointing triangle is displayed in the column header.
b) Click on the Sample index column header again to sort in descending order. A downward pointing triangle is displayed in the column header.
Sorting the Right Table by Sample Name
a) Click on the Sample name column header. The table is sorted in ascending order and an upward pointing triangle is displayed in the column header.
b) Click on the Sample name column header again to sort in descending order. A downward pointing triangle is displayed in the column header.
Sorting the Right Table by Variable Type
