table-recognize-region

table-recognize-region is an interactive autoloaded compiled Lisp function in `table.el'.

It is bound to <menu-bar> <tools> <Table> <Recognize> <in Region>.

(table-recognize-region BEG END &optional ARG)

Recognize all tables within region.
BEG and END specify the region to work on. If the optional numeric
prefix argument ARG is negative the tables in the region become
inactive, meaning the tables become plain text and lose all the table
specific features.
