 	default to color output.
 	Same as `--color=never`.
 
+--column[=<options>]::
+--no-column::
+	Override column.ui settings. See linkgit:git-config.txt[1] for
+	syntax. `--column` and `--no-column` without options are
+	equivalent to 'always' and 'never' respectively. This option
+	is only applicable if `git tag` is used to list tags without
+	annotation lines.
+
 -r::
 	List or delete (if used with -d) the remote-tracking branches.
