__call__(self, lines)[source]

Return an iterator over the table lines, where each iterator output is a list of the split line values.

Parameters:
lines : list

List of table lines

Returns:
lines : iterator
join(self, vals)[source]
process_line(self, line)[source]

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
