But on this particular column in the table I want event category filter in google data studio report. Is it possible?

Answer 1

Not sure what you want to do but it you want to have different filters for 2 columns in one table, you can use data blending. If you have data source A and wants filter1 on one column and filter2 on the other, blend Source A with filter1 to SourceA with filter2. You just have to configure the Joint Keys properly to make it give the data you are expecting.
