Importing tables not working

Until this evening, I have been able to paste sections of Excel and the forum software has accepted them as tables (such as here.)

Tonight, however, the forum software simply does not respond to any attempt to paste directly from Excel (so the best I could do was this). I can paste from Excel to the forum at Velorooms, and I can paste text into my post here, so I don't think that there is an issue on my laptop with the function.

Any solutions?
