It looks like you can go into each column and edit the label to be the same as your db, but I don't see a way to do this by default across all columns I'll request this feature internally
Thank you for looking into it, Tess. The problem is I can't work with the new table component if this questionable "feature" can't be disabled because it messes up our CSV import and export workflow. For now I will stick with the legacy table.
The latter, I'm referring to a column's mapped value.
Matthew's point is similar – the Label field seems to be automatically populated with a reformatted version of the Source field (in the screenshot, I did not remove those underscores nor change case). I pretty much always customize the label anyway, so it's not much of a change for me. But if you prefer the label to match the source, like Matthew does, you'd have to manually revert each label.
The Mapped value field now includes the {{_.startCase(item)}} by default for some column types, so you have to go and delete for those columns if you want the column to display the data "as is" from the data set.
Quite a few "whoa, why does that look so weird" moments before drilling down and removing the startCase reformatting.
