regex help

[Lance Hoffmeyer]

I have the following table and I am trying to match percentage the 2nd column on the 2nd Tiger line (9.0).

I have tried both of the following.  I expected both to match but neither did?  Is there a modifier
I am missing?  What changes do I need to make these match?  I need to keep the structure of the regex
the same.

TIGER.append(re.search("TIGER\s{10}.*?(?:(\d{1,3}\.\d)\s+){2}", target_table).group(1))
TIGER.append(re.search("^TIGER.*?(?:(\d{1,3}\.\d)\s+){2}", target_table).group(1))
