table--probe-cell

table--probe-cell is a compiled Lisp function in `table.el'.

(table--probe-cell &optional ABORT-ON-ERROR)

Probes a table cell around the point.
Searches for the left upper corner and the right bottom corner of a table
cell which contains the current point location.

The result is a cons cell (left-upper . right-bottom) where
the left-upper is the position before the cell's left upper corner character,
the right-bottom is the position after the cell's right bottom corner character.

When it fails to find either one of the cell corners it returns nil or
signals error if the optional ABORT-ON-ERROR is non-nil.
