Embedded Sheet on webpage showing more than Selection

[Affo01]

Hi all,

I am helping with a website showing league tables which are embedded Excel selections. The thing we have noticed is that even though the selection only covers the actual tables themselves, when you open the webpage, you can scroll to the right which shows an area not selected.

Can anyone enlighten me as to why this happens and can it be fixed please?

Here is a link to an example. You can see that you can scroll right into an empty area. The cells selected only cover the blue/black coloured squares. In this case AH2:AQ25.

Table example

Thanks in advance.
