Actually this is not possible to do with the block editor. However it is still possible to do if you go to your toolset settings and enable the classic editor for your view.
Go to Toolset -> Settings and scroll to "Editing experience" and enable the option "Show both the legacy and Blocks interface and let me choose which to use for each item I build"
This should allow you to setup the tables with the sortable columns.
Hi Shane. Does this mean that if I started building it in the Block interface, I have to re-build the view in the Legacy interface? Or can I switch back and forth between the 2 interfaces?
