Removing features from the exampleTable operator

I have a question if there is any operator I could use for removing features from the exampleTable?
This derives from the problem that whenever I use an operator such as discretization in a loop or x-validation etc. it generates and adds new features to the exampleSet and exampleTable. However when in next iteration these discretized features are not required then they still exist in the exampleTable. So my idea is to free (remove) these new generated features and make a space for next iteration.
If I'm wrong then please correct me.

    Hi Marcin,

    Select Attributes is your friend. If you activate the invert parameter, the selected features will be removed instead of being kept.

    Best regards,

    Thanks for the answer, and for the hidden behavior of Select_Attributes
