I can't sort the column numerically (positive and negative numbers)
How do I do that?

Hello,

If you use "ARI Data Table" table widget ("Choose table type" parameter is set to "ARI Data Table") then populate "ARI Data Tables -> Columns Settings -> Column index" with zero-based index of column which requires numeric sorting (for example if it is the second column then populate the parameter with 1 value) and select "Numeric" in "ARI Data Tables -> Columns Settings -> Sorting type" drop-down.

but there is no choice numeric see. jmp.sh/jO5sOfF

Numeric is the same as digit?

We wrote about "ARI Data Table" widget (select "ARI Data Table" in "Choose table type" drop-down). Your screenshot is for "ARI Table Sorter".
