Aligment of text in table footer

I just wanted to add a footer displaying the sum of data showing in a table column.
Numbers in the table are right aligned (which I think is the default way to display numeric data)
However the content in the footer is left aligned and I can't find a way to right align it.

How do I set the alignment for the footer? 
Wouldn't it be more sensible to align the footer in the same way as the column?

Kind regards
Jan
 

Any feedback would be appreciate.
Thanks
