sortable-columns="true"

[ghost]

sortable-columns did not work on my table. I had to add

sortable-columns="true"

which is not listed in the documentation, found this from some old issue connected to visual repeat and sortable.

However now

filter together with

virtual-repeat="true" animate-sort-icon="true" sortable-columns="true"

works perfectly.

Great work

Thanks for this, I kept checking my code for hours thinking why it's not working but the problem was I had not put sortable-columns="true" in it
