BUG: read_clipboard() on excel shifts values to the wrong column when there are nulls in the first column (original) (raw)

Code Sample, a copy-pastable example

copy this text, or data from excel/libreoffice with the same shape

col1	col2
1	red
    blue
2	green

In [3]: pandas.read_clipboard() Out[3]: col1 col2 0 1 red 1 blue None 2 2 green

Problem description

Using read_clipboard() on excel data when there are null values on the first few rows of the first columns causes pandas to use the default separator instead of the "\t" used for excel.

The result is the values shift into the wrong column

Expected Output

In [4]: pandas.read_clipboard() Out[4]: col1 col2 0 1.0 red 1 NaN blue 2 2.0 green

Output of pd.show_versions()
