typo in the IO documentation
see [stackoverflow ](http://stackoverflow.com/questions/12021730/can-pandas-handle-variable-length-whitespace-as-column-delimeters/12022047#12022047) for more.

The [read_table documentation for white space](http://pandas.pydata.org/pandas-docs/dev/io.html#csv-text-files) should have a backslash in it.  

wrong way:
data = read_table('sample.txt', sep = 's*')
right way:
data = read_table('sample.txt', sep = r'\s*')
