lines : list

List of table lines

join(vals)[source] [edit on github]

Remove whitespace at the beginning or end of line. This is especially useful for whitespace-delimited files to prevent spurious columns at the beginning or end. If splitting on whitespace then replace unquoted tabs with space first
