table component - how to make all columns sortable?

Greetings.

Table component with 4 columns.
Sort Data : True

But only columns 0 and 3 sort when the header is clicked.

I see 'Sortable Column' as a property and tried adding (4) items to it with 0, 1, 2, 3 as values, but that did not work.
Tried adding the text label of one of the columns, but that didn't work.

I am having trouble locating documentation on this component and haven't found a thread on this forum addressing the issue so though I'd start one.

In sum:
Q: How can one make all columns in a table component sortable (click on the header and it sorts low to high, or high to low)?

Many many thanks!
