Answer 1

戴兹有它。你需要使用的是pd.read_fwf。对于您的示例数据，这是开箱即用的：

names = ['TR', 'USER NAME', 'TR Mode', 'Date', 'Narration', 'Amt', 'Mode']
pd.read_fwf(file, header=None, names=names)

     TR USER NAME  TR Mode        Date Narration    Amt           Mode
1  Jeff  Thomoson        0  11-28-2018  Payments  2,400  Wire transfer
1  Jeff  Thomoson        0  11-29-2018  Interest    100        account
1  Paul    Simson        0  11-12-2018  Payments  1,000  Wire transfer
1  Paul    Simson        0  11-18-2018  Payments    140    net banking
1  John      Sans        0  11-28-2018  Payments    300         cheque

如果仍然有解析错误，您可能需要使用宽度稍微捣乱。
