i discovery that the problem is linked to this line
Table.SetColumnsWidths(Array As Int(25%x, 15%x, 9%x, 14%x, 9%x, 14%x, 14%x))
the sum of array is 100%, but the drag is enable, if i set the sum to 99%, the drag is disabled.
is it a bug o i use the class incorrectly ?
in the project is the table into color page
