In Table Filter vs Filter Panels

I have a question regarding In Table Filter vs Filter Panels. Context is for extremely complex data tables.

If a table has Filter Panels, would it be useful to still retain In Table Filters? If so, can you give me a use case as to why and companies that might do this? Just to be clear - by In Table filters I mean when there is a filter on each column of a data table. (Note: filters in the In Table Filter would sometimes overlap with the ones in the Filter Panel)

I've given this some thought and have my own idea here, but don't want to influence what everyone else might think. More so exploring this idea.

Thank you!
