The sorting of number columns in HUI data tables seems to be incorrect. I have a column containing the integers 1 through 19, which when I sort smallest to largest appear as below:
1
10
11
12
13
14
15
16
17
18
19
2
3
3
4
5
6
7
8
9
So it appears it is sorting them as strings i.e. on a digit-by-digit basis.
