Data Table shows as expected when editing, in Preview Mode it only shows the border of the table.

Hopefully someone can help! As the Subject explains, really struggling with a Data Table. It needs to be (completely) hidden until a selection is made in a ComboBox, and this then dictates which of three tables (from different Data Sources) are then displayed.

I've tried publishing, restarting, different browsers. I've turned off the Preview "Explicit Columns" setting.

This is the form with no selection:

This is the view in edit when an item is selected in the combobox:
But this is what I get in Preview , or when published:
It's a simple form to amend single records in separate SharePoint lists. Any help would be gratefully received!
It shows blank if I keep OnVisible to true, but highly likely I've done something really stupid!

Sussed it. Appears the column visibility needs to be set to true. Would say it's a glitch not working the same in both views though?!
