Hide column header in Visual Table and Matrix

[fbcideas_migusr]

Sometimes its needed to hide column header in Visual Table and Matrix and show only Grid without any headers

I would add I'd like to be able to hide only some of the column headers in a matrix.

Example: hide the Parent column of '2024' while still displaying the Children columns of 'Jan', 'Feb', 'Mar', etc.

Thank you.
