Handle failures on column filters more gracefully

With certain inputs it's possible for filters to fail, however we
should still display the table as well as return the data we have even
if it didn't go through one filter successfully.

We're still expecting "filters" to be made of functions, therefore the
func_name attribute should exist.

Note that this warning message being displayed still indicates that
there is a programming error somewhere that should be fixed.
