Sorting date formatted as string

[jakubbares]

In Javascript the only way how to format a date seems to be converting it to string.
How can then a date as string be sorted in correct way just by clicking on the column header?
Is there a way in angular data table to sort with an external function? Or sort the column by external data and using the same index?

Same issue here. Did you solved? I am thinking, do sort behind and disable sorting in table.
