For 3.13 to open data table click on chart and Cntr+D, not shift+D or right click on chart and from dropdown select datatable, once datatable is open backfill will be done.
By "Are you able to open data table with Shift + D using v 3.13."
What, I want to ask, whether you are getting data table by pressing Shift + D in v 3.13 as we get in v 3.11, or not
or
only the indirect way as mentioned by you.
