"Deleted Column" in Analyze Calculations

I’m trying to optimize the performance of a big doc with Analyze Calculations.

Spinning down the log for one of my tables, I see a grayed out “Deleted Column” listed, eating 45ms.

Am I losing performance to… a no-longer-existing column? :sweat_smile:

Hm. Haven’t seen this but Coda data file format has this capacity to store deleted columns (i.e. there is a flag for columns that are deleted). Maybe it’s like with recently deleted rows — they remain in the doc for another 24-48 hours in case you need to restore them?

Are there any references to that column that you didn’t clean up? (filters, formulas)
