Copying HTML table to spreadsheet software loses top left cell

[pwaller]

Right now, if you copy the HTML table representation of a DataFrame from Jupyter to Google Sheets or Open office Calc, you lose the top left empty cell (and the top left cell gets the first column name, which is incorrect).

Inserting an   into that cell prevents this from happening. Would a PR be accepted which did this?

One way of achieving this is to set BLANK_VALUE to  . In Google documents then, the pasted cell is present but empty. In open office, the resulting cell has a single space in it (which seems OK).

I don't know what the wider implications of setting BLANK_VALUE are - I just want to set the upper left portion of the table so that the heading is correctly aligned when I copy the table. So maybe there is a better way?

Maybe it's also possible to achieve the desired effect by modifying the CSS on the .blank class?
