**Masking Pattern:** Masking functions should be defined in Java regex pattern. Some patterns are defined by default.

**Column Type:** The masking policy is applied according to the column type. The correct column type selection is required to apply masking.


**Hide Column:** The checkbox allows columns to be hidden for any applied method.
