Order a column in a data table

Hi,

I have a data table that has a range E6:N736 (Incl Headings). The data table works well however I would like to order the last column ie column N in asc order. I've tried to select the data table and order however it doesn't allow me to do so. Ideally I would like a button that mimics F9 and then orders the data table as described about.

Any ideas?

Thanks
