Antoine Pitrou created ARROW-3656:
-------------------------------------

             Summary: [C++] Allow whitespace in numeric CSV fields
                 Key: ARROW-3656
                 URL: https://issues.apache.org/jira/browse/ARROW-3656
             Project: Apache Arrow
          Issue Type: Improvement

            Reporter: Antoine Pitrou

Pandas allows whitespace before and after numbers in CSV files, but Arrow doesn't:
{code:python}
>>> s = b"a,b,c\n12 , 34 , 56\n"
>>> pd.read_csv(io.BytesIO(s))
    a   b   c
0  12  34  56
>>> csv.read_csv(io.BytesIO(s)).to_pandas()
        a        b       c
0  b'12 '  b' 34 '  b' 56'
{code}
