Special cell values:
If the result from the printer function is too wide for the cell and
the following cell is
nil, the result will spill over into the
following cell. Very wide results can spill over several cells. If
the result is too wide for the available space (up to the end of the
row or the next non-
nil cell), the result is truncated if the cell’s
value is a string, or replaced with hash marks otherwise.
SES could get confused by printer results that contain newlines or tabs, so these are replaced with question marks.
Confine a cell to its own column (
allows you to move point to a rightward cell that would otherwise be
covered by a spill-over. If you don’t change the rightward cell, the
confined cell will spill over again the next time it is reprinted.
When applied to a single cell, this command displays in the echo area
any formula error or printer error that occurred during
ses-recalculate-cell). You can use
this to undo the effect of t.
When a printer function signals an error, the fallback printer ‘"%s"’ is substituted. This is useful when your column printer is numeric-only and you use a string as a cell value. Note that the standard default printer is “%.7g” which is numeric-only, so cells that are empty of contain strings will use the fallback printer. c on such cells will display “Format specifier doesn’t match argument type”.
