Python / Pandas：使用Regex过滤行

Question

我试图通过排除Amount包含的任何行来过滤此DataFrame？或 - 符号如下所示：

  table = table[~table['Amount'].str.contains('-|?', na=False)]

   Date        Description                               Amount   AutoNumber
0  3/17/2015        WW120 TFR?FR xxx8690                 $140.00     49246

4  03/13/2015       LoansLibro Credit Union              $155.84     49248

我正在寻找的输出是：

   Date        Description                               Amount   AutoNumber
0  3/17/2015        WW120 TFR?FR xxx8690                 $140.00     49246
0  03/16/2015       Payroll DepositDOLLARSDIRECT         $200.00     49248
4  03/13/2015       LoansLibro Credit Union              $155.84     49248

但是，我收到以下错误：

  File "C:\Python27\lib\re.py", line 251, in _compile
    raise error, v # invalid expression
sre_constants.error: nothing to repeat
