How can I read in pandas such ASCII formatted table:

      ----------------------------------------------------
      |   col1         col2         col3          col4   |
      ------------ ------------ ------------ -------------

I noticed this answer using read_fwf(), but it requires to manually specify the widths of columns:

Answer 1

Assuming that your ascii data is in a string, x:

In [1099]: x
Out[1099]: '      ----------------------------------------------------\n      |   col1         col2         col3          col4   |\n      ------------ ------------ ------------ -------------\n 1002 0.402397E-01 0.883513E-02 0.450885E-01 0.118748E-02\n 1003 0.105235     0.474509E-02 0.118508     0.168397E-03\n 1004 0.102625     0.225842E-02 0.317864E-02 0.997383    \n    1 0.603750     0.475112E-01 0.679590     0.114713E-02\n    2 0.534171E-01 0.119815E-01 0.600187E-01 0.830949E-04\n    3 0.283291E-01 0.119353E-01 0.317530E-01 0.243996E-04\n  104 0.739759E-02 0.463873E-02 0.827061E-02 0.145207E-05\n     -----------------------------------------------------'

A few options available in pd.read_csv can get you to this dataframe:

   In [1123]: pd.read_csv(StringIO(x), sep=' ', skipfooter=1, skiprows=1, skipinitialspace=True).drop([0])
Out[1123]: 
      |          col1          col2          col3      col4  |.1
