enum StructureHeaderColumnType {
    Unselected = "UNSELECTED",
    Selected = "SELECTED",
    Custom = "CUSTOM"
}

This enum is used for the Structure Matching functionality to indicate which columns should be utilized (initially) in the matching.

SELECTED columns are used for the Structure Matching. The cells in the UNSELECTED columns are initially ignored during matching but can be included by the user. Custom columns are ignored and cannot be included in the matching, these are columns created from Flag rules and State-based rules. Both Unselected and Custom columns are visually distinguishable from the Selected ones by a diagonal stripe pattern over their cells, indicating that they are ignored.
