In fact even that doesn't seem to be particularly useful if the first
column has variable width contents. The values are packed together on
each row indendently, so each row is just a bunch of concatenated text
instead of distinct columns. But I really want the columns to be
aligned, so that it's more obvious that part of the text is from the
second column.
