Modification - Total row for table

[Devaney]

Can we add a total row to the table component?
Would it be best to add it as a tfoot element e.g. lg-table-foot ?

@Devaney seems like a good thing to add 👍

As per current implementation of the table head I would use the tfoot HTML tag and then add the component with a selector of lg-table-footer.

Looks good to me.
