enhancement(tables): split formatting vs evaluation

[guillep]

add formatting block to columns.
Evaluation resolves the projection of the object to show.
Formatting returns the string representation to show.

Why is this important

This is important because sorting works on top of the evaluation.
Otherwise, if the sorting works on the string representation, the sort blocks should (re) parse and rebuild the original object to sort.

Otherwise, the (alphabetic) sorting of numerals or other will have the following sorting:

"Invalid alphabetic sorting of numeric values from the string representation"

100KB

Instead of the expected:

"Valid sorting of numeric values independently of their formatting"
