sortAscending property
final
Whether the column mentioned in sortColumnIndex, if any, is sorted in ascending order.
If true, the order is ascending (meaning the rows with the smallest values for the current sort column are first in the table).
If false, the order is descending (meaning the rows with the smallest values for the current sort column are last in the table).
Ascending order is represented by an upwards-facing arrow.
Implementation
final bool sortAscending;
