I'm having an issue with Table View in that a sheet with 498,000 cells will not add a new column into the sheet. Theoretically, this will push the sheet to about 510,000 cells.
I was under the impression that Table View has a capacity of 1M cells. What are the actual upper limits for Table View, columns, rows and total cells? (without opting in to large-scale sheets [which I cannot figure out how to enable]).
