    (print-table data &opt columns header-mapping column-mapping)
    Iterate through the rows of a data structure and print a table in a 
    human readable way, with padding and heading information. Can 
    optionally provide a function used to print a row, as well as 
    optionally select column keys for each row. Lastly, a 
    `header-mapping` dictionary can be provided that changes the 
    printed header names by mapping column keys to the desired header 
    name. If no mapping is found, then the column key will be used as 
    the header name. Returns nil.
