UNSORTABLE attribute
The UNSORTABLE attribute indicates that the element cannot be
selected by the user for sorting.
Syntax
UNSORTABLEUsage
By default, a TABLE container allows the user to sort the columns by a
left-click on the column header.
Use the UNSORTABLE attribute to prevent a sort on a specific
column.
Makes sense only for a field that is used for the definition of a column in a
TABLE container.
Example
EDIT c01 = item.comment, UNSORTABLE;
