Command Reference: addheading

Adds headings to a table

addheading takes a list of parameters and adds them to the start of a table. Where prepend is designed to work with arrays, addheading is designed to prepend to tables.

Usage

Examples

» tout: jsonl '["Bob", 23, true]' -> addheading name age active
