Description Nick Burch 2015-07-31 19:18:02 UTC
Currently, it isn't possible to evaluate SXSSF formula cells

It would be good if, for cells that contain formulas which are within the window, and where all referenced cells are within the window, you could evaluate the cell. This would allow certain kinds of formulas (eg nearby relative ones, pure-function ones) to be evaluated just after the cell is created.

As of r1693664, it's now possible to evaluate SXSSF formula cells, provided that the cell and all others it depends on are available in the current window (so both created and not yet flushed)
