Just like Header in TableRecords, would be very userful if were possible to add a Footer (tfoot tag) in TableRecords.
Some times it's needed to add a SUM at the end, today we need to get TableRecords columns with fixed width and add some new Container with fixed width just to add the right information.
Seems to be easy do something like this.
