Yes, several. Cut, paste, sed, ed, vi, emacs, perl, awk, gawk for starters.
The simplest is cut. It can be used if there is a unique column separator
character, or if each column has a fixed width padded with blanks.
The cut man page will help.
$ man cut
If the table has mixed tabs, blanks, etc in the whitespace, its harder.
