Extra Columns in Excel (OneNote)

Hi community,

I am working on an Excel sheet in OneNote 2013 (Insert -> Spreadsheet).

OneNote embeds and shows the Workbook properly, except that some extra columns are visible on the right, which are empty and I don't want to see them.

I have tried to resize the area, however it actually resizes the container of Excel workbook, distorting the font size and making it hard to read.

Is there any way to set/limit the number of Excel workbook columns OneNote displays?

Thanks in advance.
