Styling requires the colpos to be set to the string 'unused'. To preserve type safety in the
    controller, the string is only used in the template by setting the below "colpos" variable.

    {f:if(condition: column.unassigned, then: 't3-grid-cell-unassigned')}
    {f:if(condition: '!{column.active} && !{column.unused}', then: 't3-grid-cell-restricted')}
    {f:if(condition: '!{column.active} && {hideRestrictedColumns} && !{column.unused}', then: 't3-grid-cell-hidden')}
