 Output is formatted to a width specified as number of characters. The original
 name of this option is --columns; this name is deprecated since v2.30. Note that input
 longer than \fIwidth\fP is not truncated by default.
+.IP "\fB\-d, \-\-table\-noheadings\fP"
+Do not print header. This option allows to use logical column names on command line, but keep the header hidden when print the table.

 Specify the columns delimiter for table output (default is two spaces).
