How do you handle column names having spaces in them when using pd.read_clipboard?

This is a real problem I've faced for a long time.

Take this dataframe:

         A         B  THRESHOLD
       NaN       NaN        NaN
 -0.041158 -0.161571   0.329038
  0.238156  0.525878   0.110370
  0.606738  0.854177  -0.095147
  0.200166  0.385453   0.166235

It is easy enough to copy using pd.read_clipboard. However, if one of the column names has a space:

         A         B     Col #3
       NaN       NaN        NaN
 -0.041158 -0.161571   0.329038
  0.238156  0.525878   0.110370
  0.606738  0.854177  -0.095147
  0.200166  0.385453   0.166235

Then, it is read like this:

          A         B       Col  #3
0       NaN       NaN       NaN NaN
1 -0.041158 -0.161571  0.329038 NaN
2  0.238156  0.525878  0.110370 NaN
3  0.606738  0.854177 -0.095147 NaN
4  0.200166  0.385453  0.166235 NaN

How can I prevent that?
