When using the "Text import (configurable)" file type upon opening a file (e.g. a CSV file), the final dialogue allows to define the formatting on a per column basis. One has the option to change the formatting of a single column and then apply "Copy format to right" from the context menu. The command is executed, however, the change in formatting is not reflected in the user interface, i.e. the labels for the changed columns still reflect the previous formatting.
