The problem is that he's trying to consume human-readable output.  The
alignment in this output is done with spaces, not tabs (as Org would
expect).  There are more problems considering that the numbers likely
lose precision in this format (nota bene: there are other Babel
languages that have that same problem).

Since there are no tabs in there, it is impossible to skip empty cells
like the first one (they'd have to be written as "" instead, as would be
cells that should contain literal spaces).

The package already has CSV export, so one could use that.  I don't know
if you could echo the result directly to the output, all examples
revolve around putting the CSV into a file.  For Org, TSV output would
be more natural.
