[data-export] Filter results by column

[thornsteinCBS-CX]

Is your feature request related to a problem? Please describe.
Due to general SOQL limitations some fields cannot be filtered in a query. Therefore we need to run the query without the desired "WHERE" condition. The "Filter Result" search box can be very helpful in those situations, but unfortunately we have no option on which field from the query result the filter should be applied to.

Example: Query on OpportunityFieldHistory to compare NewValue and OldValue WHERE OldValue = 'Closed Won'.
BUT "OldValue" cannot be filtered in a query. Therefore I run the export without any filter on those fields. If I want to filter the result after the export by using the "Filter Result" search box, it returns all rows that contain 'Closed Won' either in the field "NewValue" or "OldValue" although I just want to return the rows where OldValue = 'Closed Won'

Describe the solution you'd like
A "Filter Result" Search Box above each column in the Export Result

Describe alternatives you've considered
The existing "Filter Result" Search Box in combination with a new picklist next to it, which contains each field from the query, to be able to apply the filter to only a single column
