You said the column values were separated by space characters.
Copying the text from gmail shows that some column names and column
values are separated by single spaces (e.g., between x1 and x2) and
some by multiple spaces (e.g., between x3 and x4. Did the mail mess
up the spacing or is there some other way to tell where the omitted
values are?
